Flex is a yellow cherry picker.
Flex is a yellow cherry picker with black stripes, a flexible arm and basket and roof-mounted lightbar.
Flex is friendly and interested in horticulture. He has extensive knowledge of plants. He prefers for the plant to be called either by its common or scientific name as shown in Lofty's Banana Tree. This was shown when Lofty named his banana tree "Mr. Banana Tree" and Flex kept correcting him to use the scientific name instead.
- Flex being a plant expert may be a reference to him being a cherry picker.
- His mouth plates appear to be recycled from Roley's model.
