Puffer-Cheep

Puffer-Cheeps are purple varieties of Cheep Cheeps that appear in Mario & Luigi: Superstar Saga. They are found on the Oho Ocean Seabed. The Nintendo Power guide refers to the Sand Cheep as a "Puffer-Cheep" or Puffer Cheep ; the 'actual' Puffer-Cheeps are erroneously referred to as "Puffy Cheeps". )

In Mario & Luigi: Superstar Saga + Bowser's Minions, they and their base form are replaced by Spiny Cheep Cheeps, which similarly toggle between standard and spiny.

Battle
These Cheep Cheeps attack at first by ramming into Mario or Luigi, who have to jump to avoid or counter it; Ifidamaged, the Puffer-Cheep puffs itself up, revealing spines that prevent the Mario Bros. from jumping on it. In this form, it will attempt to ram into the Mario Bros. again, which must be countered with the hammer this time; the Bros. will be poisoned if the attack hits or if they attempt to jump on it without the proper badge. If the Puffer-Cheep is damaged again, it reverts back to its original Cheep Cheep form, which was simply called "Cheep Cheep". If it is jumped on without the proper badge or hits a Bro, they may become poisoned.
