The Steptoe Zone is possibly a Zone on Mobius. It may lie close to the Eldorado Zone. When attempting to catch The Leaf, Tails set up a plan that consisted of a "Golden Bike Frame" being transported from Steptoe to the Eldorado Zone in order to be displayed at the museum. In reality, the priceless exhibit was actually a rusty bike frame painted gold and was probably not from the Steptoe Zone at all.
