Critter Crunch

This trophy will be awarded when you unlock survival mode, which is unlocked near the end of adventure mode. Specifically it is unlocked after clearing the 13th main path node (Bluffs Buffet) of 15 total. This will be awarded over the natural course of the game if you just keep clearing the main path adventure levels.

Since each node has three adventure levels and one bonus puzzle and one bonus challenge, and you only need to clear any three levels, it is probably fastest to just beat the challenge and puzzle levels and the first adventure level rather than beating the three adventure levels at each location (which are generally longer, and the later adventure levels in a set are usually harder). However in getting the other trophies you will need to get all adventure levels and all challenge/puzzle levels done anyways so it doesn't really save any time in the long run either way.
