Shy Guy
Do a ground pound to change his colour.

White Shy Guy
He will follow Yoshi. If he’s around when you clear a course...

Miss Warp
There are four of these on each course. Hop on her head to wake her up, then jump up to warp to the next awake Miss Warp in numerical order (1→2→3→4→1). If you lose a Yoshi, you will restart from the Miss Warp with the highest number.

Pak E. Derm
Ground pound near him to knock him over so you can pass.

Poochy
This cute little guy reacts to areas where items are hidden.
