Skall Heyho (a misromanization of "Skull Heyho") are enemies that appear in Yoshi's Crafted World. They are Shy Guys wearing skulls. They use these skulls to protect themselves as well as to hurt Yoshi. They appear only in the level Dino Smash, in which they relentlessly chase after Yoshi. If the horn on the tip of a skull touches Yoshi, it hurts him. Yoshi can jump on the back of the skull to stun them, but they cannot be defeated. Skall Heyho can also unintentionally help Yoshi by charging through and breaking dirt blocks in the way. There are Dinosaur Skulls along the way Yoshi can wear, allowing him to defeat other enemies and break dirt blocks. However, while wearing a skull, Yoshi is incapable of throwing eggs.
