Den

Den is a Diesel who works at the Diesel Works with his friend Dart. Like most of the other Diesels, he is gruff and cheeky. But deep down, he is willing to help.

Take n Play Model
Den's Take n Play model was released in 2011. His model is short for his size and has a semi-happy face.

Appearances
Den appeared in the 15th season. Oddly, he will introduced in Day of the Diesels, which is released in September. So the audience of the 15th season wouldn't know who he is. He also appears in Season 16 and might appear in Blue Mountain Mystery.
