Bishop Rock Lighthouse, Isles of Scilly - S2.E41

It's a dark night and Glitch is flying his Grim HQ over the sea around the Isles of Scilly. He's in the middle of reading a bedtime story to his Grimbots when his lamp breaks. He needs a new light, and when he sees the Bishops Rock Lighthouse in the distance he demands that the Grimbots get him the bulb.
