They are known to cause trouble for the Pack Members and also the engines; but are sternly scolded by Miss Jenny when they are found out! Despite being unruly at times with dangerous stunts, they have a good side in them somewhere and still do the work like everyone else. They are painted red and grey and have the numbers 15 and 16 respectively.
