Pestnut (Oho Ocean)
From the Super Mario Wiki
Pestnuts are small, round, plant-like enemies that are found in Oho Ocean in the game Mario & Luigi: Superstar Saga. Pestnuts are covered in spikes, making them impossible to Jump on unless one is wearing any of the "Spiny-Killer Jump" Badges. The spiky creatures can attack by rolling into their target from the front or behind. Although it is slightly stronger than the green version, this variety is also faster than the weaker variety and can also poison the Mario Bros. with its attacks. A weaker variety of Pestnut with green spikes but no poison, can be found in Chucklehuck Woods.
In both forms, after the Pestnut takes enough damage, the spikes fall out, revealing a Beanie or Gold Beanie underneath. However, any revealed from this form will float away, although it still gives out its usual item drops.
