Captain Planet and the Planeteers (1990)

S4E6 Wheeler's Ark

The compassionate Planeteers have been rescuing homeless animals globally, and when Gaia tasks them with returning endangered species to their natural habitats, they discover these environments are critically threatened. To Gaia's astonishment, rather than releasing the animals, the Planeteers return to Hope Island packed to the brim with a Geocruiser overflowing with wildlife, a sight that would make Noah proud.
