Proto:The Bugs Bunny Birthday Blowout
From The Cutting Room Floor
This page details a prototype version of The Bugs Bunny Birthday Blowout.
This is a very early build of The Bugs Bunny Birthday Blowout, then known as The Bugs Bunny Birthday Bash. Layouts for the first four worlds have been worked on, though it isn't possible to complete any of the stages at this point.
Unfortunately, the only available release of this prototype is a bad dump, though efforts have been made to repair the ROM.

Sub-Pages
| Stage 1 The most complete stage, but that's not saying much. |
| Stage 2 The obligatory desert stage. |
| Stage 3 The volcanic stage. Watch out for lava! |
NOTE: Stage 4 is badly corrupted, so it can't be compared to the final game's Stage 4 easily.
Gameplay Differences
- There is no title screen in the prototype. The game throws the player to Level 1-1 immediately.
- All objects, including Bugs, are about half the speed they are in the final. This also means that the floating platforms have their ranges halved, making some sections impossible to cross.
- There is no lives system in the prototype, so it's not possible to get a Game Over.
- The only icons that work at this point are the carrots. Bugs cannot interact with any other icon.
- Bugs does not dive in and out of tunnels in the prototype. The tunnels behave much more like the pipes in Super Mario Bros.
- There are two debug functions available. Hold Start when starting the game to get a stage select menu. Hold A to go to a preliminary version of the Mole Game.
- The moles in the Mole Game cannot be hit, and the game will continue indefinitely.
Graphical Differences
General
For graphics that appear in multiple levels.
| Prototype | Final |
|---|---|
The disappearing platform in the final was a more complicated spinning platform in the prototype. The design was simplified to make room for Bugs' diving animation. Note that while the platform "disappears", it still spins, so if you were ever wondering why those platforms had weird collision...now you know.
| Prototype | Final |
|---|---|
The graphics of Bugs and the balloon's basket were improved for the final version.
| Prototype | Final |
|---|---|
The...whatever that is...in the prototype was changed to a heart in the final. Since Bugs can't interact with this in the prototype, it's not known if it would have served the same function.
| Prototype | Final |
|---|---|
This bomb enemy was changed to an alarm clock. Same function, though.
| Prototype | Final |
|---|---|
Elmer's nets were given more detail in the final.
Title Screen
While there is no title screen in the prototype, the graphics are present.

Applying these graphics to the final gives the image on the left. The chains are larger in the prototype, the letters of the title have some shading that was removed in the final, and there are little squares around the border.
Mole Game
| Prototype | Final |
|---|---|
The mole game has actual moles in the prototype. The graphics were altered into Willy The Weasel.
| Prototype | Final |
|---|---|
This change altered the title graphics as well. The unique graphics from the prototype were replaced with a rather plain-looking textbox in the final.
Level 4
| Prototype | Final |
|---|---|
The pipes in this stage are thinner in the prototype.
Level 5
| Prototype | Final |
|---|---|
The titleset for Level 5 has no power-up icons in the prototype. The inclusion of those icons meant that some graphics had to be removed, so the second tile for the tree trunks in the prototype was overwritten in the final. The trunk was also given some additional shading.
| Prototype | Final |
|---|---|
Another victim of tile overwriting. The unique spike graphics were changed to the simpler 8x16 spike tiles used in other levels.
Level 6
| Prototype | Final |
|---|---|
The lip of the vase was changed slightly in the final version.
| Prototype | Final |
|---|---|
The (American) football was redrawn to look more like a...well, football.
Ending
Again, there's no ending in the prototype, but the graphics are there.
| Prototype | Final |

Bugs' eyes were redrawn to remove the cross-eyed look of the prototype.

The Roadrunner and Pussyfoot were removed from the photo in the final, probably because they don't actually show up anywhere in the game. Taz's oddly proportioned stomach was fixed in the final.
Unused Graphics
Graphics that are mostly absent from the final version.
Mole Game
Various tiles from the Mole Game. Some of these tiles were kept in the final, while others were overwritten. The "SORRY" message doesn't appear in the final.
Speedy Gonzales
Yep, it's him. His sprite only appears in the prototype, though there doesn't seem to be an object associated with these graphics.
Spiked Ball
Just a simple spiked ball.
???
These odd tiles take up a character bank in the prototype. It's unknown what they would have been used for, or if they were even intended for this game. These graphics were replaced with the Game Over and copyright tiles in the final.
Audio Differences
Music
There's an extra piece of music in the prototype which is used while Bugs walks into frame.
| Prototype | |
|---|---|
| Final |
The death jingle is 20% faster in the final.
| Prototype | |
|---|---|
| Final |
The World 3 song has a 2.5-second intro which was removed from the final track.
| Prototype | |
|---|---|
| Final |
The bonus stage song in the prototype has a different ending, and is about 5 seconds longer than the track in the final.
Sound
| Prototype | |
|---|---|
| Final |
Bugs' hammer sound in the final has a Square2 component, which is not the case in the prototype.
