I noticed that the Omnitrix has been screwing up a little bit regarding forms. Like in Kevin Elevin today when He wanted Four arms, he gets heatblast. Also, when he wants Stinkfly, he gets Fourarms.
In fact, I think it started in the Krakken when he was in the water and he wanted Ripjaw, he gets XLR8 and in Tourist Trap when he wanted another form (More or less likly heatblast) he got Upgrade and in the comercial for the next commercial he wanted a nother form and he got Heatblast.
So unless Ben is Bad at this sort of thing, There is something wrong with the Omnitrix or there is something we all don't know about, post comments here
