"I know you mean well, Stanley, but the mental stress just causes his brain more of a challenge, not the hot sun. You might as well teach this shovel to read. Go ahead, Zero, take it. It's all you'll ever be good for. D-I-G What's that spell?"
―Mr. Pendanski taunting Zero. (Movie)
Mr Pendanski Box

At Camp Green Lake

Pendanski is the camp counselor of tent D and “Dr. Pendanski" in the movie.He starts off as a pretty nice guy but his nice guy facade wears off soon after he finds out that Stanley is teaching Zero how to read and Pendanski starts to mock Zero for his so-called lack of intelligence. Right before Zero hits Pendanski with a shovel, Pendanski kept mocking Zero by giving him simple words to spell. He asked Zero "What does D-I-G spell?" to which Zero whacks Pendanski with a shovel and yells at him "Dig!" and then subsequently runs away from Camp Green Lake. This leaves him with a large gash across his nose. In the movie he is referred to as Dr. Pendanski but at the end it is revealed that he is, in fact, not a real doctor. He along with Mr. Sir and The Warden are all arrested since it was found out that Mr. Pendanski deleted Zero's files under the Warden's orders.

After Camp Green Lake

What happens to Mr. Pendanski after getting arrested is unknown. He got arrested being a slave owner at Camp Green Lake, endangering the campers, impersonating a doctor, destroying Zero's files and possibly some other unknown charges along with Mr. Sir and The Warden. He is in prison because of these charges.
