Here is what AZ has to say about Grompo:

grompo is basically a supur crazy creature he only walks around a lot like a crazy person and hes made of houses and TVs.

He has a TV cable thingy on his head so he can send cable TV to all the people. He likes to send out The Pink Panther and Curious George and Max and Ruby. He sends the news to every grown up.

He also has a weather vane on his head so people can see what the weather is when he walks by.

Grompo eats tomato. It’s not his favorite, but his boss told him to eat it, so he can get more shows on him. And every news. So he eats it for breakfast every day with his coffee. For lunch he eats more tomato. And he eats more tomato for dinner, too.
