The hero Jim also has a brother, Jeniysa. Jeniysa is less lazy, and even taught his younger brother everything he knows. Jeniysa has a slightly lower pitched voice then the hero Jim. In appearance, Jeniysa is more orangeish and claws are more curved. The pupils are a little bit bigger, and his fur is less spiky. He is only playable in the mini-games and 2 player of Jim of the Floating Isles.
He was also originally unnamed in the beta version of it Collector. Still told to be the GREEDY Jim of the colony, he travels too and either teams up or fights with the Collecting Jim. He had different voice acting from the Jim, as well.
