Unikitty may be an innocent show on the outside but has very inapropriate jokes for a kids cartoon.
- In the episode 'Space Mission: Danger', A black hole says get into the gravity of my hole!
- In the same episode, Mark the spaceship traps the Uniteam out in space. Mark asks if Hawkodile, Richard and Puppycorn are all Dr Fox's boyfriends. Puppycorn says yes.
- In the episode Little Prince Puppycorn Unikitty tells Hawkodile to bend down.
- In the episode 'Fire and Nice' Unikitty is singing a song and three heart sparkle matters explode on her face.
- Every time Fee Bee gets flowers she acts drunk. In the episode Sparkle Matter Matters, Unikitty and Dr Fox give Fee Bee Flowers so she can produce sparkle matter. They look concerned before they give it to her.
- In Batkitty, when Unikitty realises how safe the Unikingdom is, the citizens start kissing eachother on the lips.
- In Rock Friend, Puppycorn tries to make friends with a block citizen with a triangle citizen on his head. He then puts the triangle citizen on his head and they scream.
- In Sparkle Matter Matters, Unikitty throws a Happy Potion on Richard to make him happy.
- A literal slime ball in the episode Kaiju Kitty starts gooshing on the citizens.
