Chuggers with amazing transformation

• Wilson: By pressing his horn, water is "sprayed" and a large fire truck appears. The side parts can be manually pulled revealing the rescue tools.
• Brewster: By pressing his horn, an excavator appears. The side parts can be manually pulled to reveal his support.
• Koko: You pull him back and with a pull back motion, he quickly moves forward. The side boosters can be manually pulled outward.
