The Bugs Bunny Crazier Castle

Hack of The Bugs Bunny Crazy Castle


With five new cutscenes, revised graphics and twenty-eight enemy characters (instead of four), this hack is an impressive expansion of the original.

More characters. More cutscenes. More crazy.

What’s up, doc? You’d be crazy to miss this new release of the classic Kemco NES game.

Our hero Bugs Bunny needs your help on a daring quest to rescue his main squeeze, Lola Bunny, who’s been caught in the clutches of the despicable Witch Hazel. You’ll meet twenty-eight Looney Tunes characters along the way. And watch out - those rascals are right on your cotton tail. It’s an all-star cast. You never know who you’ll run into in the Crazy Castle!

Hop through sixty stages, collecting carrots and other items. It’s a crazy chase up creaking stairs, through doorways, and up and down pipes. Collect a boxing glove to throw a rabbit-punch, or knock your enemies out with crates, heavy safes, water buckets, bombs and ten-ton weights. Grab a Magic Potion for temporary invincibility. You might even shrink down to take on smaller enemies. Don’t let anything stop you - once you’ve collected every carrot, you’ve won!

And if that’s not enough for you, the hack is compatible with bonus level packs which will beef the game up with hundreds of extra stages. If you’re fast enough and clever enough, you’ll win every stage and have Bugs and Lola hopping happily together again. On with the show, this is it!

  • Sylvester the Cat, Yosemite Sam, Daffy Duck, Merlin the Magic Mouse

A great hack that adds more new stuff to Bugs Bunny Crazy Castle

Reviewed By: BugsBunnyFan10Trillion on 25 Jan 2023

This is a wonderful Bug Bunny Crazy Castle Hack, it adds more enemies than just Sylvester the cat, Daffy Duck, Yosemite Sam and Wile E Coyote. Other characters such as Taz the Tasmanian devil, Beaky Buzzard, Marvin the Martian, Gossamer, and Elmer Fudd are in the game too.

I hope that the people that made this game eventually make Bugs Bunny Crazier Castle 2 for the Game Boy.
