Think about it, it would improve the movie so much.
Also about that arm thing, just imagine what awesome stuff you could do with that. You could start out the movie with him only showing 2 arms, but at around the second act of the movie, he ends up in a fight against Jetpack-Ninjas (believe me, Jetpacks and Ninjas improve anything!), so he does some smooth Kung Fu style asskicking with two hands, before whipping out a pair of golden Desert Eagles chambered in .50AE, blowing fist-sized holes into anyone that's giving him lip.
The main badguy could grab his own two weapons and point them at Wogglebug, just as he whipps around his arms. As they stand there, surrounded by dead and dying mooks in a mexican standof, with sparks from the light fixture above raining down in the cold fluorescent light of the seedy brothel that they just wrecked, the bad guy rumbles "Looks like we're evenly matched" and Wogglebug just whips out his other two arms holding guns as well. Man, that would be so fucking cool, the kids would love it! All we need is to add a Schwarzenegger-like one liner. Maybe "I raise you two guns", but that lacks refinement, admittedly.
It's also a strong moral lesson to never underestimate other people and to not pick a fight in a rundown thai ladyboy brothel with a regular customer that's a battlehardened veteran such as the Wogglebug.
Well, you could showcase that by having him build traps and outsmarting his prey.
