Moon Rocks was a scam in "No Speak Da Ed." Eddy charged 25¢ per moon rock (which was really gum obtained from the bottom of the school cafeteria's tables, painted turquoise). The scam failed when Eddy tried selling the moon rocks to Kevin, who struck back at Eddy for annoying him. The Urban Rangers interrupted to deliver pen pal mail. Later, Eddy sent the fake moon rocks to his pen pal, who paid him with loads of Korean money, which was worthless to Eddy in its foreign state, as the Candy Store threw it back to him when he tried to use it to buy Jawbreakers.
