One slight goof, maybe
So, bake lady tricks Wallace into falling for her by, possibly, deliberately have him save her from a broken bicycle.
We see Gromit try the brakes and they worked just fine, implying there was nothing wrong with the bike... but on the way down the hill, we saw her try the brakes to no effect.
So, did they fail because she didn't try them and they left that scene in by accident... which begs the question of "did she know a crocodile would be involved in her plan?"
Or
Did the brakes not work because she was fat? Which is in poor taste for Wallace and Gromit.
I think it's a joke
