"We ain't toyin' around with you, now scram!"
Funhouse Frazzle is one of two Run-and-Gun levels in Inkwell Isle Two. It is near the Die House that leads to world 3. It can be accessed after beating either Carnival Kerfuffle(which takes you directly to the level) or using the shortcut around the back of the isle, in which case the player(s) must beat Sugarland Shimmy first.
- A hallway with two floors. The pink cards seen floating can be parried to switch from floor to floor.
- A short section that is uneven where stars that have cannons attached to them shoot bullets in a cross formation.
- A wonky hallway with floors that move on their own. The player must parry the pink cards once again to swap floors.
- A line of four toy cars that drive down the first hallway. They cannot be destroyed but can be avoided by flipping to the ceiling or floor.
- A giant toy duck going down the first hallway with two toy ducklings following. One of the ducklings following can be parried. The giant toy duck can be destroyed by shooting at its head. It can also be ducked under to avoid damage to both the player(s) and the duck(s). This option may be a pun on ducks, as the player is literally ducking (or crouching) under a giant toy duck.
- A green and white checkered wall with one eye and two mouths. It can only be defeated by shooting at its eye. In the first section, the wall will open one of its mouths and have two toy cars drive out of it. In the last section, it will stick out its tongue shortly after telegraphing with an "Uh-Oh!" sign instead. In both of the sections, the wall will shoot out a kissing mouth with a horn. Player(s) can pass through the wall without fighting it by going through one of its mouths after it opens them.
- A star with four cannons around it, it shoots bullets around in an X-direction or a +-direction.
- A little rocket with a wheel, it will go up or down if the player is above or under them.
- A box with an eye and four spikes, a head will pop out of it like a jack-in-a-box with the spike shot at the player after it spins for a short time. The head can pop out in 4 directions, indicated by which direction the eye is looking towards.
- Jacks with an eye replacing each knob. Some of these jacks can be parried.
- A giant tuba that shoots out a physical onomatopeia out of its horn, "BWAAAAA!!!"
- The cars coming out of the wall's mouths are similar to the ones in the 1952 cartoon Susie the Little Blue Coupe, as well as other cartoons featuring anthropomorphic cars.
- This is the only level in which the player fights the same mini-boss (the two-mouthed wall) twice.
- The style of the stage is inspired by the artworks of surrealist painter Salvador Dali, who notably worked in the film industry with Walt Disney, as well as Alfred Hitchcock for the 1945 film Spellbound.
- The sentient tuba may have been inspired by the tuba prince of the Isle of Jazz from the 1935 Silly Symphony Music Land as well as the lead character from the 1947 Puppetoons short Tubby the Tuba by stop-motion pioneer George Pal.
- The Lobber weapon will still function under regular gravity and fall to the bottom floor if the player(s) fire the regular weapon or its EX move.
- The tuba's attack has five A's and three exclamation points.
