The Temple of Juatchadoon is an ancient temple situated in South America. It was first seen in Phineas and Ferb and the Temple of Juatchadoon. Ohio Flynn and Rhode Island Fletcher went there, with Candace, to find New Hampshire Garcia-Shapiro and recover the ancient amulet of Juatchadoon. After that all was a trap by Damsel in Distress Isabella and Doofenshmirtz. On the temple lives the ancient corn giant. The temple was destroyed when Ohio broke the amulet.
- It was destroyed in 1914 but is seen rebuilt during the song Summer All Over the World which takes place in the 2000s.
- Some of the traps of the temple are parody of Indiana Jones movies
