Electro Tile

Electro Tiles (also referred to as "Electros") are similar to Spikes in every way except they go faster and can't hit UFOs. When the Electros are shocking, they can kill Stinkers and enemies. Electros can be set from speed 1 to 4 with speed 1 as fastest and speed 4 as slowest. Unlike their Spike counterpart, they do not have Metatiles that operate slower speeds of Electros for it just ends at speed 4.
