The girls visit a golden train on a field trip and set to eat lunch, but find the Professor refused to pack them anything sweet. When a vendor offers them free ice cream, the girl are more then happy to accept... except the vendor turns out to be Mojo who tainted the ice cream to both give the girls instant ice cream headaches and be extremely addictive as well. Now the girls must overcome the lure of the ice cream while trying to stop Mojo.
Tropes
- Evil Tastes Good: Mojo's ice cream. Despite instantly freezing the girls, they can't stop licking it.
- Gone Horribly Right: Mojo steals the gold train and melts it down to turn into a wrecking ball. But ends up getting tangled in it when trying to untangle the rope which causes it to activate and slam him through various buildings. And since the girls are having trouble getting over his ice cream and him having set up stands to stall them, it takes awhile for them to save him.
- Harmless Freezing: Licking the ice cream instantly freezes the victim into a block of ice.
- Here We Go Again!: At the end of the episode, Mojo sets up a chocolate stand with the girls considering trying it.
- I Can't Believe It's Not Heroin!: Mojo's ice cream turns out to be quite delicious that the girls have trouble resisting it.
- Loophole Abuse: The hologram message of the Professor tells the girls they're forbidden to buy anything sweet. But the "vendor" tell them the ice cream is free.Girls: Yay! Loophole!
- Low Clearance: Once heading for a tunnel, Mojo hops back into the caboose of the train while the girls break free of their latest freezing just in time to slam into the top of the tunnel entrance.
- Paper-Thin Disguise: Mojo's vendor outfit is nothing more then him in a mustache and a silly hat, yet the girls don't recognize him.
- Shout-Out: One of the citizens looks like Lars from Steven Universe.
