Its sad to say that I don’t think they’ll add that. They are planning to add more colors so there will be more max players in a server, so if the players have pets, its like playing with twice as much players, which is totally unfair.
That would unbalance the game so much bc imps would have to kill every1 twice and if you get voted off every1 would know if ur imp or not and if u get killed by an imp you'd know who the imp was and I don't have a pet and I'm not going to buy one so that would make the game pay to win
