The Mole

The Mole was Grandma Tracy's electric scooter.

It was mentioned, twice, in Oh Dear, Miss Malone, before actually making an appearance in Meet Me At The Spot, a Grandma-centric episode.

The Mole is a yellow scooter, with several drills perched on the front to chase away any 'slow-bodies', as put it by Grandma herself in the second episode of BTS. It reached a top speed of 112 miles an hour.

It was destroyed in the Season Two finale, The End, along with most of the regular craft.
