Salem the skunk

Salem's only appearances in Chapter 1 is as a torn cardboard cut-out in Rambley's Railway, and as a sprite in the Rambley Rush arcade game, where they're depicted as unprincipled and evil. They're shown experimenting with potions on the wildlife of Rambleberry Woods as well as Mollie Macaw, with the stated goal of doing so being to make Mollie forget her friendship with Rambley and have her kill him. Victims of Salem's corruption turn purple and hostile, and develop unknown abilities. The corrupted version of Mollie becomes the boss fight of the arcade game, which breaks down after the player or Mollie runs out of health.
