On this page, you will find a detailed description of how to obtain "Tiny Trounced" bronze trophy in Crash Bandicoot 3: Warped for PlayStation 4. You receive this trophy for defeating the first boss of the game - Tiny Tiger.
Right after the battle starts, you will have to escape from the boss's attacks. He keeps jumping all around the arena. You also should avoid his attacks by jumping around. Keep doing that until the boss tries using the trident and jabs it into the ground. The trident will get stuck (the above screenshot) and this is your opportunity to deal some damage to Tiny Tiger. Run up to the boss and Spin-attack him to do damage.
Tiny Tiger will now escape from the arena and will start to send smaller tigers after you. Try to be prepared for that and stand in the bottom-left corner (the above screenshot) or or in the upper-right corner.
After you spot the tigers, do not move, because they can slightly divert from their route and get to you. Remain by the left, or right, edge of the arena and Spin-attack each time a tiger comes close enough (the above screenshot). you have to kill 4-5 tigers this way before the sequence ends.
The rest of the battle follows the same pattern. Wait for your opportunity to Spin-attack Tiny Tiger and avoid the smaller tigers. Damaging Tiny Tiger for three health points ends the battle.
