The Piranhas are the hungry fish from SPY Fox in "Dry Cereal".
SPY Fox in "Dry Cereal"Edit
Mr. Udderly was left dangling under the piranhas' pool in the Feta Cheese factory at some point after he was captured. In order for SPY Fox to save Mr. Udderly, he must lower the temperature control to absolute zero in order to freeze the pool and keep the piranhas from biting Mr. Udderly. Right after SPY Fox lowers Mr. Udderly, the piranhas prepare to eat Mr. Udderly until he is moved away from the pool.
