As if the show, comics and toys were not enough, the commercials of Transformers G1 also end up falling into this trope. Two in particular stand out; the very first one, using entirely different models for The Ark, Megatron and the Seekers. And this one, which truly showcases how much of an ExpyJetfire was. This Chile commercial also contains a gratuitous amount of this trope, though this is because neither Toei or AKOM provided the animation.
An M&Ms commercial from Madagascar (the country, not the movie) has horrible-looking models of the M&Ms mascots; they're completely hollow on the inside with no tongues and they appear lumpy whenever they move their limbs.
