The cactus creatures first appear in "Memories of Boom Boom Mountain." The mother cactus creature declares she must be pollinated to make her babies, and Finn causes a chain of events that does so. Once the creatures are born, the Dragon uses the baby cactus creatures to scratch its itchy behind.


And I need to be pollinated. Pollinated all over to make my babies!

Pollen! Here they come!
