My school actually allows tamas! (only tamas on mute, that is) but I stopped bringing mine ever since someone “borrowed” my Gigapets remake (they broke the battery slots😞)
Also, If you are looking for something easy, I would recommend any of the tamagotchi nano series pets. Nanos do not take much skill to take care of, just feeding, playing, and scaring away predators, which make your tama sick. Good luck!👍
