With the recent changes to the Art making so yordles now having 4 fingers Amumu is confirmed to be also a yordle, Though I don't remember seeing his art in the -patch notes seeing it now in the client it is all but confirmed.
I guess this means that Ivern, Renekton, Blitzcrank and Twitch are yordles too then.
Glad that's cleared up.
the shop keeper on the howling abyss has always called him a yordle. it was heavily implied before, but I guess the 4 finger thing confirms it.
Amumu already had 4 fingers on all of his splashes, this was just a process for fixing Yordle splashes who had 4 fingers
