Banana? Really?

Hey guys! I was on the Ninjago official website and I was reading on the products page. One of the captions said this:
Help Cole on a mission against the mighty Fangpyre Mech! Fang-Suei has the golden Fangpyre staff in his clutches but swiping it won’t be easy. Battle Fang-Suei in the giant Fangpyre Mech with razor-sharp fangs, powerful grabbers and missile launcher! Use Cole’s special golden scythe and special kendo armour for protection! Includes Kendo Cole and Fang-Suei minifigures, Fangpyre Mech, golden Fangpyre staff, exclusive golden scythe and banana.
And on the picture you see the Mech, Fang-Suei and Cole. Cole's holding what I think is a Tri-Scythe and a banana.

A banana? Really? What do you need a banana for? I don't why they actually included one in this set. I guess you could make the banana special if you pretend its a bomb or something. I thought it was a fang blade at first. If I recall corectly, I did not see one banana in either seasons of Lego Ninjago. Weird huh? If you have an idea put a comment below with your idea! ;)
