This croaking frog is already open with its mouth to eat your egg yolk! It sucks the egg yolk in and if you squeeze his belly, he spits it out again. Very handy if you are baking, for example, and you have to remove the yolk from an egg. Squeeze the cute frog and bring its open mouth to the egg yolk and then release the frog. The frogmouth sucks the egg yolk in the silicone frog mold. Do you want the egg yolk back? Then you just squeeze the frog’s belly again and he will spit out your egg yolk again for you!
