If anyone has suggestions for different rules, I would be happy to read them. If anyone has advice to make the story better, go ahead and tell me. Sorry if there are grammar mistakes in these chapters, my phone likes to rewrite my words.

Rule number seven: Katsuki and I should not laugh like maniacs at Hisashi Midoriya after a prank. (In front of our mothers at least.)

Izuku Midoriya talked to Katsuki Bakugou about pranks he could pull on his dad.

Inko Midoriya was getting frustrated. Lately things had been moved in her kitchen and around the house that shouldn't be moved. Then one of her dresses disappeared, a green sleeveless dress. Of course, that meant she needed to visit her friend and talk about it.

Mitsuki Bakugou was getting annoyed. Her son kept asking her for ways to change hair products or how to dye hair. It was unnerving for her to hear Katsuki say that he wanted to dye his hair red like his explosions.

It was the day after they put the clues together.

At first it was a regular day. Katsuki Bakugou had come over to play with Izuku. Hisashi was in a deep sleep and didn't come out until one o'clock...The mothers were talking to each other when Hisashi Midoriya came out of the bedroom after screaming a high pitch voice.

He had on Inko's green dress, had red, spiked hair, and colorful sharpie drawn whiskers on his face with one eye having a circle on it.

Now the question that everyone had was how it happened.

The boys room opened up and both women could hear laughter. Izuku looked out of breath and was hitting the wall after falling to the floor on his knees. Katsuki was rolling on the floor and laughing like it was the funniest thing in the world.

When they asked Katsuki: "I just put watercolor paint on it."

When they asked Izuku: "He had the dress on when we were in there. I put the whiskers and circle on."

If anyone had watched them:

Izuku Midoriya his mom's favorite dress with the hanger and put it in his closet.

Katsuki bribed his dad to buy paint.

Izuku took his mom's colorful sharpies and put them on his desk and covered it with his notebooks.

Katsuki bought permanent hair dye with his allowance when his dad wasn't looking. "It was just a toy that I can share with Izuku!"

Izuku put two sleeping pills into a peanut butter and jelly sandwich for his dad to eat. The man ate it without noticing the pills because of the thick peanut butter. With that he fell into a deep sleep when he hit the pillow.

That was how both children were grounded from visiting each other for a month. Even if both mothers found the outcome hilarious.
