Catzilla Mod brings giant monster cats into your world. This mod lets you turn normal cats into huge beasts using uranium from deep underground. You can tame these massive creatures, ride them into battle, and use powerful attacks to defeat your enemies.

Catzilla Mod

Features:

  • Uranium Mutation: Mine uranium ore near bedrock and feed it to a normal cat to transform it into a giant monster.
  • Explosive Taming: Use large amounts of TNT to knock out the beast, then feed it massive amounts of uranium to tame it.
  • You can ride the tamed monster and use a basic swipe attack with the left mouse button.
  • Players can hold the sprint key and left-click to perform a tail spin that sends enemies flying.
  • Pressing R makes the monster roar, throwing anything in your path away.
  • Holding G unleashes the Atomic Breath, a powerful beam that destroys blocks and deals heavy damage.
  • The beast has a rage meter that fills up when it takes damage from other mobs.
  • If the rage meter gets full, the monster kicks you off and blasts everything nearby before passing out for 10 minutes.
  • You can breed two tamed monsters using uranium to get a baby version.
  • Killing an untamed monster drops special items used to change your tamed pet into different forms.

Monster Types:

  • Use an Oxygen Tank to get the 1954 form, which blinds enemies and deals faster breath damage.
  • Apply a Freeze Bomb to unlock the Burning form, which sets targets on fire and has a massive shockwave attack.
  • Feed a Noobfish to get the Tremorzilla form, a glowing green beast that can charge forward to knock enemies back.
  • Use a Pocket Watch for the Legendary form, a tough monster that can grab enemies and blast them point-blank.
  • Apply an Evolution Candy to get the Shin form, a slow but super strong giant that heals itself over time.
  • Give it an Alert Sign to unlock the 2000 form, a fast and agile beast that attacks quickly.

How to Use:

  1. Go down to the bedrock level and mine uranium ore.
  2. Right-click the ore with a pickaxe, then use a brush to extract the uranium.
  3. Find a normal cat and feed it the uranium to mutate it.
  4. Blow up the giant cat with TNT until it passes out.
  5. Feed the knocked-out beast more uranium to tame it.
