what is this nonsense rito

So it says in tahms description or champ spotlight or somewhere, that he can't eat blue buff, red buff, dragon or baron, because he can't fit it into his belly, but somehow, the tahm in my game, fit a full 6 stack cho'gath with an iron elixer active, that dude is bigger than blue and red combined, lol, maybe he should be able to eat red and blue, but only of he has 3 stacks, and it slows him if he eats it aswell, maybe not 95% but a good slow, cause rocks and tree monsters are heavy ^_^
