Bugs can be collected by using Russell. When near a bug or butterfly press the
Button – Russell will use his net to catch the bugs and butterflies. In order to finish the quest cards you must collect a certain number of each bug in the game. Butterflies can be found on various stages flying around. The bugs are typically found by breaking logs, mushrooms, and various objects in the game. Make sure you keep Russell as your playable character (use the
to change characters) and try to catch all the bug and butterflies you see. If you have been making an effort to collect the bugs and butterflies you should unlock this achievement by Level 7.
