The Alligators Exhibit is one of the Jungleland areas in the Cartown Zoo. It has an unfinished bridge with an alligator in the middle. There is also a vine that Putt-Putt uses to jump across the other side of the unfinished bridge.
Putt-Putt Saves the Zoo[]
When Putt-Putt first arrives, he must use the vine to get across the unfinished bridge, so he can avoid falling into the water (although the alligators living there don't seem to be hostile).
