Twonkie

From Jimmy Neutron Wiki

Carl, Jimmy and Sheen around a twonkie

Twonkies are a life-form from a comet Twonkus3. They are small cute beings, but when they hear any music they turn into vicious monsters. When some twonkies aren't in freedom, or trapped they turn into one big almost indestructible monster.They are similar to Mogwais eating after midnight to turn into Gremlins when Twonkies listen to music to get bigger.


Reproduction

A twonkie coughs out babies, but nothing more is known about this process.


Reaction to external sounds

Twonkies turn angry when they hear music, but only if it's pleasant. For example Sheen's singing makes them sleep.
