There's a poro and a snail behind him at the blue side fountain near appa
I don't know if it has always been there, someone in a match pointed it out though :|
Going to print screen it, and while I'm at it going to check if there's any wildlife at the red side
EDIT: I made a custom match but the poro wasn't there T_T. When me and my team saw it we were 5 anivias though.. might be special interaction
