Frame Boo

Frame Boos only appear in 6-5 or Yoshi, the Terror of All Boos Yoshi's Woolly World. If Yoshi hits them with a yarn ball as he is turned the other way and being chased they will turn into Boo like balloons and float up a bit. They will then regain their normal forms. They can never be destroyed. Yoshi can turn them back if he wants by hitting the bow on the balloon with his tongue. These are exactly like Big Frame Boos.

Description
They are boos that are made of frames and yarn. The center of the frame glows. It changes from red to blue when Yoshi is looking at them or not. They are red when Yoshi is looking at them and blue when they're chasing him and Yoshi's isn't looking at them.
