Most levels in the game are based around various Looney Tunes shorts.

Level 1.1 (Level 1)

A snow forest level where Bugs battles Elmer Fudd and his hunting dogs, as well as the Goofy Gophers. Defeat Elmer by punching him in the face with a pie and then scurring down a rabbit hole. While in the rabbit hole, Elmer will shoot a bullet that will miss the player. When the player emerges from the ground, he should repeat this process. When you get enough hits, Bugs will stick his finger in the barrel of the gun, causing the bullet to fire back at Fudd's face.

Level 2.1 (Level 2)

This level takes place in a saloon bar. The Red Hot Ryder and Hiawatha cameo as one of the enemies here. Bartenders try to trick the player by sliding beers down the counter tops. Big holes in the floor can only be crossed by jumping on nearby TNT barrels. The barrel will explode and the lid will fly skyhigh. Before the player can do battle, he should post a "Bugs was here" sign. Nasty Canasta from Drip-Along Daffy awaits Bugs at the end. To win, stick next to him and jump up on him repeatedly. The final blow will send him down a hole in the floor.

Level 400 (Level 3, Boss Level)

Toro the bull from the animated short Bully For Bugs is here. It's best to go to the right first. Stop in front of a bulls-eye target to lure the bull near the player. Jump up and right out of the way just in time for the bull to smash into the target and not Bugs. The bull will be dizzy from the impact, so quickly head to the next target. When the player reaches the right side of the arena, grab the 1 and the anvil and start heading to the left side. Avoid the bull jumping over him when he charges. You need to jump to the right to avoid his first charge and the left on his second charge. Look for anvils and other items in the rabbit holes. On the left side, get the bull to run into the white wall to pass underneath it to reach a big switch. Flip the switch to release a metal wall on the right side of the arena. Head back to the right side, jump over the bull and drop an anvil for him to run into. Continue to the right using anvils whenever necessary. If the player runs out of anvils, he will need to use the previous technique of jumping over the bull's charges. Bugs must make the bull crash into a steel girder. An early screenshot of this level (printed in Nintendo Power issue #55) showed early Looney Tunes star Bosko as one of the characters in the audience watching the fight; he does not appear in the finished version, however.

Level 1.3 (Level 4)

This level is based around the Bewitched Bunny short. It features Witch Hazel (and her gingerbread men army who throw candy), who casts temporary spells on Bugs (one of them transforms him into Michigan J. Frog); Hansel and Gretel; the three pigs from the short the Windblown Hare, who use slingshots to throw acorns; and the big bad wolf, who tries to blow tumbleweeds, wood, and bricks at you or blow you away. At the end, Yosemite Sam shows up in his outfit from the animated short Knighty Knight Bugs, complete with his dragon. Make his dragon sneeze back several times. Then the dragon will stop charging and Yosemite Sam will fall off his dragon and smash on the ground being flattened. The Goofy Gophers also show up in this level.

Level 2001 (Level 5)

This level takes place on Martian space vehicles. Some Instant Martians attack Bugs with laser guns, which can shrink him temporarily. Bugs can deflect these shots back at the Martians with mirrors, shrinking them instead. Marvin the Martian also makes an appearance, but is oddly not featured in a boss fight.

Level 9.1 (Level 6, Boss Level)

Bugs must traverse Tasmania in this level. The Tasmanian Devil constantly tries to attack Bugs. Get the Tasmanian Devil to fall off the ground or eat exploding TNT turkeys. But he will return appearing from underground. Hop on giant parrots to get to different grounds. Head to the right side. When the Tasmanian Devil spins like a twister, jump up and have him go through trees to go further. When you get to the white tree, have him hit the tree and a coconut will fall on his head. After several hits, Bugs will dress up as a Tasmanian She-Devil and the Tasmanian Devil will fall in love with him. Then the real she-devil (whom the Tasmanian Devil married) comes in, starts smacking him across the head with her rolling pin, and drags him away.

Level ³√x÷(/_c-Z) (Level 7)

Bugs must travel through Acme's factory, facing various mechanical contraptions such as robots and ACME's Christmas gift wrapping machines. Wile E. Coyote is fought at the end.

Round 42.379⁄₈ (Level 8, Boss Level)

Bugs Bunny must fight The Crusher, the wrestler from the short Bunny Hugged, ultimately making him fall into a hole . Bugs must jump over him avoiding his charges, kick him, and spin around punching him.

Level 13 (Level 9)

There are many black cats in this level. This causes bad luck (in the form of falling objects) to follow the player wherever he goes. If Bugs hits a cat with a paintbrush pickup, Pepé Le Pew will show up to take the cat away. Sylvester appears riding a train in some parts of the level.

Is this trip really necessary? (Level 10, Boss Level)

The final level, where it is discovered Daffy Duck has been animating the entire game (not unlike in the shorts Duck Amuck and Rabbit Rampage). Bugs has to spill the paint so Daffy cannot draw anymore. While he is doing this, Duck Dodgers, Robin Hood Daffy and Drip-along Daffy try to stop him. After Bugs empties out the last of the paint, the player must strike the Robin Hood Daffy a few times before finally completing the game. If Bugs defeats Robin Hood Daffy, but doesn't empty the paint cans, he then has to fight Drip-along Daffy. If Bugs defeats Drip-along but still has not spilled all the paint, Robin Hood Daffy appears again.
