Piranha Sprout (Yoshi's Story)

Piranha Sprouts are Piranha Plants that appear only in Piranha Grove in Yoshi's Story. Piranha Sprouts are one of the few variations that have the ability to walk. They look like buds of a Piranha Plant with green feet. Their ability to walk is extremely limited to short waddles. Piranha Sprouts, like Piranha Pests, are able to shrink anything that escapes from their mouths. A Piranha Sprout makes a squeaking sound and pops out of the ground when least expected. The only known way of defeating a Piranha Sprout is by shooting it with an egg.

In Super Smash Bros. Ultimate, these Piranha Plants are mentioned briefly by Viridi in the Palutena's Guidance dialogue for Piranha Plant.

Yoshi's Story
''New species have been introduced to the Piranha Plant family, making them even more formidable. It will swallow you up and turn you into a mini Yoshi.''
