ABE or the Automatic Branch Engineer is the robotic caretaker of the Train Tunnels in Epic Mickey 2. When you first meet him, he will say that the earthquakes damaged him and the Dioramas badly. If you damage or ignore 2/3 dioramas, Abe will make Beetleworx attack you. You also recieve Steamboat Willie Pants near the end of the Floatyard (Inside a shutter near the clown head area that opens only when you destroy the dioramas).
If you repair 2/3 dioramas, Abe will give you a pin and is restored.
