When 4-year-old Rosa transforms into a 40-foot giant after finding one of the rings, it's up to Kid and Jo to keep the destructive tot out of trouble.
Tropes:
- Big Damn Heroes: Chuck, after unwittingly being freed by Rosa, manages to defeat Kid and Jo with the yellow stone's duplication powers, ties them ups and takes all the stones Kid has for himself. Just as he's about to leave, Rosa returns and manages to put up a fight against Chuck and his clones without using the stones.
- Cassandra Truth: Unsurprisingly, given her age, Rosa being unabashedly honest with her parents about what she was up to this episode results in nothing more than chuckles about what an imagination she has.
- Disapproving Look: Jo gives Kid one after he yells at Rosa and makes her run off crying after.
- Even Evil Has Standards: Despite that he doesn't dwell on it for long, Chuck voices that even he thought it was cold-hearted of Kid to yell at Rosa and tell her he wasn't her friend.
- Giant Foot of Stomping: Rose nearly squishes Chuck and Papa G after dealing with Chuck's clones. Luckily Papa G got the yellow ring and inherited the duplication powers, stopping her and saving the both of them.
- If You Kill Him, You Will Be Just Like Him!: Rosa wipes out Chuck's clones, but Papa G prevents her from squishing the original because "Heroes help, not hurt".
- Jerkass Realization: After being captured and tied up by Chuck, Kid realizes that yelling at Rosa was wrong. After Rosa stopped Chuck and his duplicates, Kid apologized to her and welcomed her as part of the team.
- Kick the Dog: When he reaches his limit with her after she unwittingly let Chuck escape, Kid yells at Rosa that he is not her friend which ended up making her cry.
- Mythology Gag: The climax involves a small superpowered child (well, when normal) going ham on a group of evil doers. Now remember who made this show and what he made before. Guess some old habits die hard.
- Nothing Can Stop Us Now!: Having read Kid's comics during his imprisonment, Chuck says "Who's going to stop me?" after grabbing the safe containing four of the stones. Such is Tempting Fate, he never counted on little Rosa returning to stop him.
- No, You: Chuck's verbal antagonizing of Kid eventually devolves into a back-and-forth of this.
- Rage Breaking Point: Kid reaches his limit with Rosa after she unwittingly let Chuck escape.
- Sequel Episode: Immediately follows the previous episode's last scene.
- Unusually Uninteresting Sight: Papa G doesn't see anything out of the ordinary of Rosa and Kid's "playing together". Despite Kid flying and Rosa being 40 feet tall.
- What the Hell, Hero?: Jo asks what Kid was thinking when he tried to hit Rosa for stealing the ring. She believes just because Rosa is gigantic and feels no pain doesn't excuse Kid from attacking an actual 4-year-old girl who doesn't know better.
