Peach Bell

The Peach Bell is very similar to the Strawberry Bell, the biggest difference, other than the colors, being that bow design with the heart in the middle and the bell dangling from it are on the bottom as opposed to the top.

Ribbon Peach Echo!
Ribbon Peach Echo, despite sounding similar to Ribbon Mintone Echo!, is actually more similar to Ribbon Strawberry Check!

Mew Peach grabs the bell and attaches a tiara to the bell part, before then grabbing ahold of it, spinning around, holding it up and calling the attack name, "Ribbn Peach Echo!". She then lands down and holds it forward as a beam comes out and attacks and/or purifies the target. During this part, the silhouette of white wings can be seen coming from the bell as well as Mew Peach herself.
