Earthworm Jim 2 (Shin-Shin) is an unlicensed NES port of the SNES/Genesis game "Earthworm Jim 2". This bootleg is a very stripped down version of the original game with only a few levels showing up, including "Anything But Tangerines", "Granny Chair", and "Puppy Love".
There are two versions of the game, one version features less levels than the other version for whatever reason. This TAS by XTREMAL93 plays on the version with more levels and beats it in record time.
We also have a TAS of the official game on Genesis.
