Pros:

It's a monkey on a bomb!
So funny that the zombies are going after a monkey
Detailed

Cons:

it's pretty big, and it covers almost all of the right side (not so much of a matter since you will choose it to throw)
No Monkey sounds (not so much of a deal)

Conclusion:

Whenever seeing a survivor pulling out a monkey bomb, it cracks me up.
Consider downloading this mod if you want some giggles before throwing that bomb!
PS: Where did you get that diamond minecraft stuff?
