Sniff

Sniffing, or the Sniff-Sniff, is a basic special move that is found in Yoshi's Story. All the Yoshis in the game have the ability to sniff.

To sniff, the player must press and hold the button to make a Yoshi start sniffing the ground for something valuable. The Yoshi can move while sniffing, but he does so more slowly than normal. When the Yoshi gets closer to something special, he starts to sniff faster; getting close to a secret causes a "!" icon to pop up above the Yoshi's head, indicating that the secret is nearby. Once the Yoshi is on the secret spot, he gets excited and begins yelping and waving his arms; the player can then ground-pound the spot to retrieve the secret.
