The BIGGEST of my Animated Dinobot set is Sludge! I wanted him to have the girth and weight that a Bronto should have so I opted to use a Grimmy as the base. Head is made from Ani Grimlocks with rounded eye ridges and filed down teeth. Lower jaw is the lower jaw from an Activator Grimmy. The neck came was an Animated Wreck-Gar leg as it had that smoothness that Animated has. The front legs are from a Snarl as well as the rear legs which form his forearms. The dino-neck has an added 180* rotation hinge that allows his "wings" to be larger than Grimlocks and to allow the dino neck to be less kibbly. Bot head is a Snarl head with styrene. 3 more to go! Enjoy!
