So I used to play awhile back and there were happy eyes I always used them but I came back after a few years only to find them gone, was there a reason for it to be removed?
Sorry if it's bothersome.
If you mean pokemon sprites in battles, there's a mod for that.
You can use it on android there might be some bugs though.
