Inkling Fireworks (Pixiv Fanbox)

"The Inkling Boy was tired of being teased all the time for losing all the Splatfests. On the 4th of July he set up a trap for his biggest teaser to get revenge. When he trips the wire, a mini rocket will destroy his pants and underwear, latch a diaper around his waist, and slam him into a huge firework at the end of the walkway. As soon as he got it set up, the person this trap was meant for spooked him from behind and made him trip over his own wire. It all happened so fast and eventually he ended up diapered and hugging the firework as it launched into the sky. "Huh?" he said, confused about what was about to happen to him...!"
