John P. Tristate Elementary is the school in which Phineas and Ferb attend. The school has barely even been seen in the show, since the series takes place in the summer. However, it has made a few minor appearances. In "Are You My Mummy?", during the song "My Undead Mummy", a scene showed what would happen if Phineas and Ferb brought a mummy to school, and all the students watched in awe as Phineas and Ferb's mummy started DJing for them.
