- Chinese title: "炸弹在身边" ("Zhàdàn zài shēnbiān")
English title: "Bombs are Everywhere"
Careless S. gets too... well... careless with his weapons at school and has them confiscated by Headmaster Tele. Meanwhile, Big M. intends to plant bombs in the school by hiding them in bricks meant for school construction.
This episode contains the following tropes:
- Axes at School: Deconstructed. While it's true that Careless S. is a superhero who uses his weapons to fight evil when it's needed, he becomes too reckless with his weapons in the school regardless and destroys parts of the building when he uses them, triggering the plot when Headmaster Tele confiscates them.
- Concealing Canvas: Careless S. has a bunch of his weapons hidden around the school after Headmaster Tele forbids him from having them on hand there. One of them is a bomb hidden in a small space tucked behind a picture of the Headmaster.
- Cyber Cyclops: When the Planet Gray virus activates within him, the construction worker, one of the normal two-eyed robot citizens, becomes a one-wheeled robot with a single, red-colored eye.
- Exact Words: Headmaster Tele declares he will confiscate any more weapons he sees on the school property, then sees Kalo using his arm to slice a watermelon and literally confiscates him (along with his watermelon).
- Fireball Eyeballs: Headmaster Tele's eyes become flames when he gets angry at Careless S. for destroying the Superstar School building with his weapon.
- Fruit of the Loon: Kalo is randomly seen slicing a watermelon, leading to Headmaster Tele locking him in a cage since he has now forbidden all weapons from the school.
- Here We Go Again!: The episode ends exactly how it starts, with Headmaster Tele saying he's taking Careless S.'s weapons from him after he uses them to defeat the villains.
- Look Behind You: Big M. pulls this trick on the mail bot to get his mail for free, and quickly locks the door afterwards to prevent the robot from getting in. It doesn't work, as the robot simply carries him off with the door he's clinging to, and Big M. and Little M. pay enough money for the mail to leave them without clothes.
- Loose Floorboard Hiding Spot: Careless S. thinks one of his weapons is hidden in a floorboard in his classroom. When he uses a toy claw to grab it from the space under the floorboard, he thinks he's latch on to not one, but two of them, but he pulls Big M. out of the bathroom in the floor below instead.
- Mundane Utility: Kalo uses his Voluntary Shapeshifting powers to turn his arm into a blade and... slice a melon.
