Chuggington - Season 1 Episode 33
Zephie's Monkey Business

Vee asks for a spare engine, and Zephie arrives first. She is to take Dr Gosling on an inspection of all the animals in the Zoo. When Emery passes by, Zephie tells him what she is doing, and Emery scares her by saying the monkeys are mischievous and will steal her wipers. Zephie is upset by this and tries to stay away from the monkeys, but then wanders into the monkey enclosure and realises that the monkeys arent as bad as Emery says. The trainees also practise using the crane cars.
