Helpful Skrill

A Helpful Skrill appears in the quest The Almighty Thor in the game School of Dragons.

Testing Electrical Resistance
When Snotlout and the player bring the Thor Statue to Snotlout's Sentry Station, lightning strikes it and nearly destroys the telescope, instead hitting an unfortunate sheep. While the sheep does survive, Snotlout and Fishlegs suggest that the player get Heather's help to prevent a similar incident from happening again.

Once the player has gathered glass from Fishlegs, rubber from Johann, wood from the Wilderness, and silver from Mulch, Heather begins an experiment to determine how much each material resists electricity. For this experiment, Heather brings a Skrill into the lab and has it blast electricity at the objects, with an Ohmmeter measuring the electrical resistance of each material. Eventually, rubber is discovered to be the best insulator, allowing the player to return to Snotlout's Sentry Station with the material and insulate the statue

Physical Appearance
The Helpful Skrill is representant for its species, being dark purple with dark blue on its wings and belly. The nasal horn, the spine crest on its head, and the spines on its back and tail are also dark purple.
