Puffer-Cheeps are blue varieties of Cheep Cheeps which are found in the Oho Ocean Seabed during the events of Mario & Luigi: Superstar Saga. These Cheep Cheeps would attack at first by ramming into Mario or Luigi, who have to jump to avoid or counter it. However, if damaged, the Puffer-Cheep puffs itself up, revealing spines that prevent the Mario Bros. from jumping on it. If the Puffer-Cheep was damaged again, it would revert back to its original form, which was simply called "Cheep Cheep". If it is jumped on without the proper badge or hits a Bro, they may become poisoned.
