Yoshi cupcrake is a fearsome and very deadly edition of Yoshi.
He eat all people but Yoko Littner who he has married. He fights the weegee monster and other gee monsters to save the world.
He is 100% fearless.
As for a stare? HE DON`T NEED A STARE LIKE YUSHEE, He just rips out parts of you and eats alive then doing soo with this teeth.
Worse, he may ask his wife for help.
