Echidnas are enemies that debuted in Crash Bandicoot 2: Cortex Strikes Back. They are small brown mammals that appear primarily in the snow levels. The echidnas attack by releasing the needles out of their back to attack Crash. While the echidnas' needles are out, Crash must avoid jumping on or spinning the echidna away since they will harm him and cause him to either lose his Aku Aku mask or a life.
There are brief moments when the echidna withdraws the needles from its back, allowing Crash to jump on them or spin them away without getting into any harm. Crash can also slide into an echidna in order to defeat them at any time. He will not take any damage during this method, even when the echidna's needles are out.
