bugs and also minecraft w !!!!

gonna eventually make a minecraft mod revolving around bugs :3 i know i definitely wanna add ants, termites & roaches and i think im gonna start working on roaches first cause right now i have most info/ideas for them. i also wanna make it possible to keep the bugs as pets !! so i think i'd have to add a like, tank item and all that... does anyone have any bug suggestions ^_^ ?
