Calm Amazing Flyin' Hammer Bro.

From the Super Mario Wiki

Calm Amazing Flyin' Hammer Brother (or C.A.F.H. Bro for short) is an enemy found on Vibe Island in Super Princess Peach.

The C.A.F.H. Bro is almost exactly like an Amazing Flyin' Hammer Brother, except this one is usually found asleep. Princess Peach will have to walk very slowly in order to keep it from waking up. Once woken up, it acts like a normal A.F.H. Bro.

According to the Glossary in the game, one should "Attack this sleeping enemy without getting close."
