Either Pack-a-punch thunder gun and shoot it, or wait for monkey round then suck them in and shoot em making an energy explosion

"Make sure it's a monkey round. Have only the stamin up perk and then when the monkeys come down yourself so they start attacking you and not the perk machine. Then Lead them into the area where the orb is. Throw out a black hole on the glowing light and then have the hole suck up the monkeys. They should explode giving it energy. Jump in it.

Bam. There you go."

I dunno if this works, but it sounds like the best solution.

If your gonna quote me guys make sure you add that when they are being sucked into the black hole you MUST shoot them to release their energy to get the power to work perfectly. then jump in.

thanks guys trying it now
