Welcome to Moist Hollows. Follow the blues, kill enemies and collect blue lifeforce (make sure you've got at least 10 blue lights). Follow the path until you see the blue Hive and spawn pit (#1). Call at least 10 blues and send them to take their hive to the waypoint. You'll have yet to save the blues you've seen on your way. So, when the blues with the Hive stop, take a few steps down the other path where you'll see the blues in danger. Recall the blues carrying the hive and call more minions from the spawning pits near by. Now, see there's an egg in the middle of the water. Position your minions down but not too close to the water. Send one blue to grab the egg and lure the birds to the other minions to kill them. Continue to the waypoint with the hive (#2).
Let the other minions ahead so they clear the path from mushrooms and other stuff blocking the way (#1). Keep in mind that only the blues are magic resistant so only they can kill the whisps - another source of blue life force. Continue your walk killing the creatures and smashing the mushrooms out of your way.
Send your minions to move the block at the bottom and this up there too (#1) - you'll access it via the passage to your left. Keep walking and remember to clear the mushroom out of your way. There's blue spawning pit ahead - as well as a water serpent to kill. Let's go get it then! Here's one way how to do it: there's browns spawning pit to your right - call as many of them as you can, but keep some blues too, to resurrect the dead warriors. Attract the serpent to attack, move back quickly and send browns to attack its head - you can support them with your powers and weapons. Don't let them stay too long on the serpent's head and call them after a few seconds - they should take a safe jump even if they're high up above the water (#2). Sometimes the monster wouldn't want to play - provoke it then until it eventually does and fight it dead.
Pick the hive and follow blues across the water (#1). Kill the frogs and other forest creatures as you walk - collect the blue force! Soon you arrive at field of geysers. Send your minions carefully to the wheel there (#2) to make a bridge so you can continue with the hive. Keep walking and smashing the mushrooms. You'll come to brown spawning pit and another field of geysers. Take blues and browns with you and head right, kill the frogs in your way and send blues to move the block at the path's end.
Come back to the browns spawning pit. There's a path across from it, a little hidden (#1) - go this way and kill the bugs as you walk. Enter the opening to the left of the waterfall so you'll come to a broken bridge. To walk further you have to get rid of these annoying birds and use the mechanism to open the bridge (#2). You can fireball the birds and send minions to turn the wheel or repeat what we've tried before: send a blue one to grab an egg and lure the birds so the others can kill them. Now walk across the newly opened bridge and send your fellows to move the rock.
Come back for the Hive (#1) - you've cleared the path but there are some mushrooms left so take them out. Once you arrive at the ramp, you'll need 10 blues to carry the hive. There are spawning pits on the left (#2). Blue is behind the rock, near by the water. And the waypoint's just in front of you!
Now that you've got the blues, let's go to Mellow Hills to get the tower object you've been passing by so many times. You can see it from the sheepies spot you know so well (#1). Go there, then, and arrange a little slaughter. Now head toward Slave Camp and take the turn behind the blood pit - follow the path down to the water and send blues to take the thing (#2).
