Shrink and Enlarge Player and Mobs with the Gulliver Mod

Minecraft mods Gulliver Mod 1.2.5

The Gulliver Mod allows you to change the size of you and the mobs and players around you. Using new potions, you can adjust your size from 1/8th all of the way up to 8 times your original size. Being small or large brings unique strengths and weaknesses. This mod works perfectly with the Little Blocks Mod.


In single player, you can adjust your size by pressing the ‘R’ key to double the current size and the ‘F’ key to halve the current size.

Press ‘R’ or ‘F’ while holding a stick to change the size of mobs.

In multiplayer you have to use a potion to adjust your size.

Press Shift-Crouch to jump half your height

Can ride other mobs by right clicking on them with String. Make sure to keep holding the String or your will fall off when hurt.
