Trash
1: Something worth little or nothing
a: things that are no longer useful or wanted and that have been thrown away
b: inferior or worthless writing or artistic matter
The excess negative emotions that are worthless to us, but valuable to the frog man was meant to be the trash. The worm mini game represented jealousy, and anger and sadness scenes were also made but due to running out of time those scenes weren't finished and the idea wasn't properly conveyed. The music also was not able to be fully implemented.
If all else fails, it meets the definition of trash by having such inferior writing and artistic implementation lol
