Putter as he appears in the cartoon.

Putter Popple is a Small green Popple who is somewhat hyperactive and has a tendency to do practical jokes but is very playful. Putter has a knack for fixing and inventing things, but they do not always work quite like he expects.

In the 80's Popples cartoon, Putter had the most appearances outside of the two lead Popples, appearing in 25 episodes.
