Umbrella (Yoshi's Story)
From the Super Mario Wiki
Umbrellas are objects in Yoshi's Story. Yoshis will usually get the opportunity to obtain them when atop a large cliff. The umbrella will allow them to glide, thus also allowing him to collect floating Heart Coins and fruit. The player uses the control stick to control the direction the umbrella falls. When Yoshi reaches the bottom of the cliff, the umbrella is dropped.
