Piranha Pod

Piranha Pods are a Piranha Plant version of Spiny Eggs. Like Spiny Eggs, they are thrown by Lakitus, but turn into a Piranha Plant upon landing rather than a Spiny.

New Super Mario Bros. U / New Super Luigi U
Piranha Pods appear in New Super Mario Bros. U in the level Blooming Lakitus, and in New Super Luigi U in the levels Spinning Sandstones and Beanstalk Jungle.

Super Smash Bros. Ultimate
In Super Smash Bros. Ultimate, Viridi briefly mentions them during Palutena's Guidance dialogue for Piranha Plant.

Mario Party Superstars
Piranha Pods reappear on the Peach's Birthday Cake board in Mario Party Superstars, replacing the Strawberry Seeds from the original Mario Party, though they are still referred to as strawberries. In-game, the term is used liberally by Lakitu to refer to both the pod itself and the Piranha Plant that grows out of it, while a Play Nintendo article reserves "strawberry" for the Piranha Pods. The game also marks the debut of Big Piranha Pods, which sprout into Big Piranha Plants.
