Caterpie my boi my beloved my precious 🙂
Early wyrm is a pun on worm and wyrm as well as a joke of it being a early version of Caterpie so an early worm pokemon and a joke on early bird gets the wyrm.
File bug is based on the Pokedex entry of Caterpie's apatite. It's a hungry virus or computer bug that eats files and code.
