Rex and Bobo are reinvigorated by the Fountain.

During an adventure with Detective Chimp, they tailed some thieves who had robbed a circus, to the Atlantic Island of Bimini. When an alligator attacked Bobo, Rex defended him but was wounded. Bobo went off and found a source of water that turned out to be the fabled Fountain of Youth. The water reinvigorated them both, returning their youth and extending their lives.[1]
