Megascooter

The megascooter replaced its ancestor in the Justin Polar Beach and spread out all over the Justin island. Due to island gigantism, the megascooter is 10 times the size of its ancestor. It has also evolved darker green skin, which allows it to absorb more heat than its ancestor. Along with that, the megascooter keeps warm with a thick coat of "plent-blubber" and it huddles in groups of 10-25 members. Unlike its ancestor, the megascooter is able to breath air, as long as it keeps its throat sac moist. For those living in the Justin Tundra, they take in small quantities of snow that melts into water, which keeps their throat sac moist. In the water, they breath it as their ancestors would. The megascooter has also evolved a third toe on its feet to help support its body better than its ancestor.

The megascooter has evolved a method of communication with its top spike being a forward-facing horn. With this "communication horn", it sends electric messages to other megascooters by touching its horn to another megascooter's horn. These messages can convey their dominance, their age, their gender, and their health. Since they huddle into one another, they have adapted their electricity to activate voluntarily. It does so with newly developed electric organs, an organ connected to each of their spines, that control the electricity they release.

Other than these changes, the megascooter is similar to its ancestor.
