You cannot do this glitch on the updated version, so delete the update.

First what you do is, obviously, get monkey bombs. Throw all of them, and you have to have grenades to do it.

You throw a grenade on the ground. When the grenade is on the ground, hurry up and press LB as if you were going to throw another monkey, but jump away from the grenade so that you wont die.

Then you will throw another monkey. After that you can teleport and get more grenades.

If you are playing with 2, 3 or 4 people, one person can throw a grenade, and everybody can use it, so there will be 2, 3 or 4 people with a monkey.
