We're in the home stretch of Super Meat Boy 3D, as only one more boss stands between you, the final world of the game, and Dr. freakin' Fetus himself. You've slain Sawhalanthropus, Mr. Filthy, and The Forge Master already. Time to add Maggot Larry to the list.

The good news is that by this point in the game, you might actually find that Maggot Larry is the easiest boss in all of Super Meat Boy 3D. At least for me, I was a bit surprised that boss number four was ultimately such a pushover in a very short and manageable fight.

If you're here, however, maybe you're still having some trouble, and there's absolutely no shame in that. Here's how to outlive this gross monster.

Maggot Larry Video Guide

The idea of this fight is that the circular arena will shrink with each completed phase of the fight. This happens a total of two times, meaning we've got a three-phaser here. No worries though, none of them are that incredibly difficult.

As we've covered in all the previous SMB3D boss guides so far, I'd recommend you take a look at the video above to really get a feel for how this fight works and how to win. If you still want some help after that, keep reading.

How to Beat Maggot Larry

Phase one is actually arguably the toughest part of this fight, simply because the timing of Larry's AoE maggot attacks is extremely quick with little to no margin for error.

Once the fight starts, you'll want to immediately move in either direction, as the first giant AoE circle will spawn directly below you. After dodging this first one, you'll have two more in total to dodge, and they alternate locations on the ground. That means you need to keep moving. Dodge one AoE, then immediately move to where it was on the ground to dodge the next incoming one before it pops out of the ground.

All the while, you'll have small tracking missiles raining on you from the sky, which makes the need to always stay moving doubly important.

After phase one, the outer rim of the floor will fall away, plus a little more for good measure. Stay towards the middle to not fall off. Next, Larry's tentacles will sweep at you from either direction. There is a trick here: If a tentacle is coming from the left, you must jump over it. If it's coming from the right, you must stay on the ground and go under it.

Keep moving and jump rope/duck accordingly, again while staying in motion the entire time, since the tracking missile will be following you again.

The floor will fall away once more, and now it's really narrow. Huge the inner portion while making sure you don't fall into Larry's toxic pool of sludge.

Larry will spawn two giant orbs of maggots, and they'll rotate clockwise. Run as fast as you can clockwise yourself, and after about 10 seconds, the fight will end. This part is easy, so don't stress!
