Bowling Goonie

Bowling Goonie are wingless Hefty Goonies that first appear in Super Mario World 2: Yoshi's Island and Yoshi's Island: Super Mario Advance 3. Instead of flying, they slowly roll on the ground as their method of travel.

Super Mario World 2: Yoshi's Island / Yoshi's Island: Super Mario Advance 3
Many Bowling Goonies are found directly on Yoshi's path, but some are the result of hitting a Hefty Goonie with an egg or swallowing it and then spitting it out. Bowling Goonies cause damage if they roll into Yoshi, but can be defeated with a Ground Pound or an egg. Yoshi can also walk on a Bowling Goonie as on a platform. Unlike Hefty Goonies, Bowling Goonies cannot be eaten. They are capable of rolling at the same speed on both horizontal and inclined surfaces and will roll off any edge that they encounter, continuing to roll on the surface underneath.

Yoshi's New Island
Bowling Goonies return in Yoshi's New Island in the level Fine Feathered Friends or Foes?. They behave and can be interacted with almost exactly like in their original appearances, the only difference being that natural Bowling Goonies will turn the other way when they encounter an edge of any kind, but those that are spat out by Yoshi will still roll off edges.
