$20 really stretched a lot farther in 1993
Bart and Milhouse bought:
1. A Super Squishee made entirely of syrup
2. Possibly a luxury skateboard (it’s unclear if they made a purchase)
3. VIP access to the arcade (with drinks)
4. Two tickets to Cats
5. Toothless Joe’s gum
6. Temporary tattoos
7. A dirty word shaved in the back of Milhouse’s head
They also could have bought many peanuts. S5E8
