Toober Guy

A Tube Guy is a Shy Guy in Yoshi's Island DS that wears a red, green, orange, or purple innertube in water and constantly looks from one side to another frantically, then moves. The only difference between it and a regular Shy Guy is that Tube Guys can be on water, making it nearly impossible to eat it, and stay on land at the same time. If Yoshi gets into the water, he can eat it easily.
