The entrance to T.U.F.F. Test Bunker in Iron Mutt

The "top secret" T.U.F.F. Test Bunker is a testing facility and tourist attraction located in the desert, that appeared in Iron Mutt. It is home to a gift shop, a buffet, and a testing site.

It was here during Iron Mutt, that Keswick unveiled the S.U.I.T. to the public. Dudley "volunteered" to be the first one to test it, much to the crowd's delight.

The bunker has not appeared in any episode since. It is unknown if it will make another appearance.


  • Perhaps jokingly, the bunker, the gift shop, and the buffet are all referred to as being top secret. The irony is, they aren't.
