The girls confront Packrat at a museum, but Bubbles' arm gets broken during the fight, so she's given a cybernetic cast by the Professor so she can continue fighting crime while her arm heals. While initially reluctant to use it, Bubbles come to like having a bionic arm. Unfortunately, the power eventually goes to her head, and she refuses to take it off when her arm heals.
Tropes
- Acquired Situational Narcissism: Bubbles as a result of the robotic cast making her more powerful.
- Artificial Limbs: Sorta, the bionic cast acts as one for Bubbles' arm while it heals.
- Attack of the 50-Foot Whatever: Packrat gets covered in toxic waste and becomes a goo-covered monster.
- Drunk with Power: Bubbles, after she comes to like the newfound power of the cast.
- I Call It "Vera": Bubbles calls the cast "Armsie".
- Nice Job Breaking It, Hero: Bubbles hitting the ground in rage causes an earthquake near the dump, which causes toxic waste to fall on Packrat, and mutates him into a giant goo covered monster.
- Sequel Hook: Packrat is still alive, and takes the broken bionic cast for himself.
- Unexplained Recovery: Bubbles can be overlooked since she's a superhero and probably could survive the cast explosion, but how exactly did Packrat both survive and turn back to normal from it?
- We Are Not Going Through That Again: At the end of the episode, Bubbles ends up breaking her leg. However, Blossom and Buttercup refuse to have her get a bionic leg cast.
