why do some of the minions in my zoo have stats? does it mean i can battle with them? 👀 i've never touched the zoo till now, honestly forgot it was a thing, and i can't find any info on it

Yes there was a minion battling feature. The ones with stats were minions at the time this was created and therefore could battle. (Honestly not sure it still works) They would gain exp and stat increases but there wasn't like prizes or anything associated with it yet. Newer minions don't have stats.
