Round 25

Information

Difficulty: easy.
Bubbles: fire, standard.
Clear fruit: doughnuts.

Strategy

Wait around at the bottom of the level until fire bubbles start to gather above you. Some of the Monstas may make their way down to where you are waiting, in which case trap and burst them. Once some fire bubbles have gathered above, jump up to burst them, but position yourself under the left-most edge of the "frying pan" so that you fall back down to the bottom of the level again.

After the fire has cleared, jump up and take out any remaining Monstas. Fill the level with bubbles before killing the last one for free doughnuts.
