From the Super Mario Wiki
Juggling Heyho are enemies in Yoshi's Crafted World. They are circus-themed Shy Guys that juggle. They appear only in the level Hoop-Jump Hop, alongside Unicycle Shy Guys. They stand in one spot, slowly juggling two to three small, colorful missiles. If one of the missiles hits Yoshi, it explodes and hurts him. Yoshi can eat Juggling Heyho to get eggs.
