4 or 5-fingered hands?
Despite Baby 'Zillas clearly having 5 fingers, ToraGoji only has 4 fingers in the actual movie, but it seems that they accidentally a 5th vestigial finger when making the [promo?] suit they took a lot of pictures of. When looking at the 3D model, animatronic, and even decided design concept art and maquette, there is no 5th finger period.
However, it would appear that sometime during suitmaking - maybe after the Baby 'Zilla suits were made and they were given the 5th finger - ToraGoji received a vestigial, 5th finger on his hands erroneously. And that 5th finger can be seen in many shots of this suit.
