Submit to the Human Show competition
Switch to Laverne and go to the lobby. In order to make it to the basement, you need to distract the purple guard who is standing near the clock. If you talk to him, you will learn that the way to keep him busy is to get him tickets to Club Tentacle. Head to the room with fireplace and talk to the blue guard. You will receive a name tag that allows you to take part in Human Show.
Head to the first floor and enter the room behind the second door. Take roller skates from the cupboard and extension cord from the plug near the door. Use the skates and the name tag on the mummy and then push it. The mummy will slide downstairs and will join the rest of the Human Show participants. Leave the room and head upstairs. Go past the participants and head right, to the jury sector.
Prepare for the competition and win it
When you talk to the jury, you will learn that the participants will be judged in three categories: the best haircut, the best smile and the best laugh. To win the first price, your mummy will have to win all three categories.
Start preparing for the show by sending the scalpel that you have to Bernard. Switch to Bernard and use the scalpel on Oozo the Clown. When there is no air left in him, take the box o' laughs from the floor. Go through the door to the kitchen and take the fork from the table. Send the box and the fork to Laverne and send textbook to Hoagie.
Switch to Hoagie and go back to the motel. Go upstairs and you will meet a horse. Use the textbook on it and it will fall asleep. Before going to sleep, the horse will take out his dentures and place it in a nearby glass of water. Take it and send it to Laverne, along with spaghetti. It will turn to soggy noddles.
Now you can switch back to Laverne. Approach the participants of the show and use the items on the mummy in the following order: first soggy noddles, next the box o'laughs and then use the fork on mummy's head to make a nice hairstyle. The mummy is now prepared to take part in the contest. However, to make sure that it wins, you have to get rid of the competition.
Switch to Bernard and go to the first floor, to the tentacle room (third door). Push the speaker on the right and play the stereo. This action will make a fake barf stick to the ceiling in the room below fall down. You can now switch off the stereo and leave the room. Head downstairs, to the lobby to collect the fake barf and send it to Laverne. Switch to Laverne and use the barf on Harold, the mummy. Harold will be disqualified from the contest for being sick. Now you can approach the jury and ask them to judge all three categories. When the contest is over, our mummy will become the winner and a dinner certificate will appear in Laverne's inventory.
Remove the Purple Tentacle Guard
Leave the room and head downstairs. Go through the room with fireplace to the cell that tentacle calls a kennel, because they treat humans as pets. Give the dinner certificate to the guard and he will leave the room. Now you have the opportunity to use the switch near the door to free Dr Fred's descendants from the cell. It will turn out that they don't want to leave it. You have to find a way to make them move.
Switch to Bernard and send Booboo-B-Gone to Laverne. Switch back to Laverne, leave the cell and go outside through the main exit. Walk to the right and you will see a stray cat. You cannot catch him, by you can use Booboo-B-Gone on the fence. This way, a white stripe will appear on the cat's body and it will resemble a skunk. Unfortunately, the animal will run to the roof.
Switch to Hoagie and go upstairs, to the loft (you can also go through the fireplace). Use Ned's bed to distract the cat. However, it will work only for a while. When you sit on Jed's bed, you will notice that the mattress doesn't squeak. Use the squeaking mattress from the first bed on the second bed to switch them. When you use Jed's bed now, you will distract the cat for long enough to take the squeaky mouse toy. Pick it up and send it to Laverne.
Now, switch to Laverne and use the mouse on the cat to catch him. You can now go back to the building and return to the cell. Use the cat and watch the reaction of Dr Fred's family. When they start running away, the purple guard will follow them. Use the opportunity to open the clock and reach the lab. Use extension cord on the generator. Use the second end of the cord on the window to place it outside. Now you have to find an animal that will power the machine.
Find the hamster that will power the generator
As Bernard, go to the second floor. Open the door on the right and enter Weird Ed Edison's room. You will find a full version of Maniac Mansion on the computer located here. You can return here at any moment in the game and continue the game from the place where you stopped. Pull out the hamster from the strange looking aquarium, leave the room and go downstairs. Approach the ice machine in the corridor and open it. Use the hamster on it and close the machine. The animal will enter hibernation state and will appear in the future.
To use it, switch to Laverne and leave the lab. Reach the first floor. Approach the machine and open it. Take the frozen hamster. In order to defrost it, go downstairs, to the kitchen (through the room with fireplace). Now go back to the underground lab and use the hamster on the generator. Unfortunately, the animal is still to weak to work. You need to find a way to make it liven up.
Switch to Bernard and open the door to the first room on the first floor. Go inside and close the door. You will notice keys in the lock. Take it, open the door again and leave the room. Go downstairs, to the lobby and leave the building. Head right. You will notice a man in ski mask trying to break into a car. Give him the keys and he will give you a crowbar. Go back to the lobby and use the crowbar on the gum with a dime stuck in it. Take the piece of gum with a dime inside. Use the gum and Bernard will extract a dime from it.
Go to the first floor of the motel and go through the first door. Inside, there is a FickleFingers coin slot in the corner. Use both dimes on it. You will make the bed vibrate and the man sleeping on it will fall on the ground. Now you can take the sweater from the bed. In order for Laverne to be able to use it, you have to find a way to make it smaller.
Leave the room and approach the candy machine. Use the crowbar on it and a whole pile of quarters will fall out. Take them all and head downstairs. Go through the fireplace room to the kitchen. Now, open the door on the right and go to the laundry room. Use the sweater and quarters on the dryer. The sweater will become smaller in the future.
Switch to Laverne. Leave the lab and get to the laundry. Open the dryer and take the sweater from inside. Use it on cold wet hamster, place toasty warm hamster in the generator. You will get hit by a boxing glove on a spring. The hamster will use the opportunity to hide in a mouse hole near the stairs.
Switch to Bernard and send the flier to Hoagie. Now, switch to Hoagie and go downstairs, to the fireplace room. Use the flier on the suggestion box. After a short conversation between the founding fathers, vacuum cleaner will be included in the constitution.
When you switch back to Laverne, you will notice that there is a buil-in shop vac in the lab. Use it on the mouse hole. Open the hatch and take the dust ball out. After cleaning it, it will become a dusty warm hamster. You can finally use it on the generator to start providing power. Leave the lab and go outside the building. Go right, to Chron-O-John and use the extension cord on it. Another task complete!
