Loudmouth

The Crescendo (ラウドネス) is an Emblem Heartless from Kingdom Hearts: Chain of Memories and Kingdom Hearts II. These Heartless can be both a pain and a gain. They have little strength, but their sounds can call in reinforcements. Their sounds can also heal nearby Heartless, but by using the Reaction Command, Heal Stomp, the Crescendo's healing sounds are directed towards Sora and friends instead!

A hopping, horn-like Heartless.

It's a bothersome foe that can honk and call other Heartless.
