This episode marks the end of Remy and Timmy's rivalry for good after Ivan explained the true potential of a kid with their godparents, which gave Remy a change of heart.
When Remy challenged Ivan for a magical duel in Fairy World and everyone left the mansion, Cosmo and Astronov, while in snail form, were trying to catch up, similar to Cosmo in the episode "Most Wanted Wish" when he was trying to reach Rock with fanfare music.
Juandissimo turned Cosmo and Astronov into snails similar to how he turned Cosmo into a turtle twice in the episode "Fairy Fairy Quite Contrary".
The Simpsons - After Remy bought a candy bar faster than Ivan could due to him being unable to think of what candy bar to buy, Ivan shouted out "D'oh!", a famous catchphrase of Homer Simpson from the Simpsons.
