This mod adds many different features to many different parts of the game. A lot of the features presented by the Random Junk mod are mostly for fun, and as such may be references to memes and other franchises, but some are unique to this mod. A few even are meant to be generalized stereotypes of certain mod types, like End mods. Some of these features include the following:

Glitched biome, with "missing texture" blocks and glitchy trees.

Three new Nether biomes, each containing a new mob and many new building blocks.

Several new End biomes, including "Space" and three forests.

Chug Jug. Need I say more?

New weapons, like the Guac Glock and Guac Clobberhead. These tools are meant to make exploration and combat more fun while also being unusual and not fitting Minecraft's normal style, becaues why not?

Magnets that launch you into the sky and can be enchanted with two new enchantments.

A new type of throwable explosive weapon that is great for mining.

Paper airplanes that can be thrown at enemies and are crafted with a single piece of paper.

Quite a few overworld biomes with different climates and features.

A few edible plants found in special locations, like a fantasy variety of pepper.

Three new bosses and unique weapons made with their drops.

An energy system made with a new metal alloy of Zinc and Tin.

And much, much more!
