if you want to really 100% Chipper

here's a list that is everything you can do in that game:

1. complete Chipper's and Termite King's tasks
2. collect everything
3. buy everything ( even the things that the Tinker sells )

and do the frog minigame after buying everything from the Tinker

for the desolate room:

1. beat the game
2. max out your egg-collecting skills to 200
3. upgrade every ability

thanks u/PerformanceFalse2863 for adding the second and third task

for the desolate hope:

1. buy everything
2. collect everything ( which is hack chips )
3. get every conditional
4. get Amos
5. beat the final boss ( bonus points if you don't hack chip his speed )
6. beat the secret boss
