The girls are set to start school but remember that Pokey Oaks Kindergarten was destroyed when Bubbles accidentally splashed an alien liquid onto the class's pet hamster, Pee-Wee, during a show and tell and caused him to grow. Thus, the girls are enrolled at a regular elementary school. Unfortunately, they're met with jeers by the older student body and request that the professor to make them older. The professor obliges, and makes some potions for them, that they were only to take a sip from. But the girls, being impatient, drank it all, and aged into seniors. However, this new change doesn't seem too bad the next day they go to school, until they need to stop Mojo's crime spree.
Tropes:
- Dark Is Not Evil: While trying to find a way to reverse the girls' aging, the Professor accidentally summons a monster, which looks like it wants to attack him...until he finds out it just wanted to play paddy-cake.
- Gilligan Cut: After the girls find out they've went overboard on the aging...Bubbles: Maybe the professor won't notice.(Cut to the dinner table where the Professor and the girls are)Professor: Of course I noticed, and I'm very disappointed in you three.
- Even Bad Men Love Their Mamas: Mojo spends most of the episode talking with his mother on a cell phone, even claiming he was stealing something for her for Mother's Day.
- Kids Are Cruel: The girls barely say two words to most of the students at the elementary school and are quickly mocked.
- Mythology Gag:
- When Bubbles flashes back to how the old Pokey Oaks Kindergarten building was destroyed, the style is designed like the original series, including Bubbles' older design.
- The scene where Professor Utonium creates the potion is similar to how the PPG came about.
- Out of Order: Unless this is an Origins Episode explaining why the girls are now in a new school, this might be the case, since the girls were already attending elementary school in previous episodes.
- Rapid Aging: What happens to the girls after they decided to drink all of the aging potion.
- Rousing Speech: Blossom gives one to Bubbles and Buttercup when they try to confront Mojo despite their old age.
- Villains Out Shopping: Before he sees the girls' aged forms, Mojo's just walking his dog.
