What is fake kibble?

Fake kibble is when you think you see part of a bot's alt mode in bot mode, but that part doesn't actually form the part of the alt mode it appears to.

Great examples:

Classics Voyager Prime - his grill in robot mode DOES NOT become the grill in alt mode.
Universe Silverbolt - On his shoulders there are little wings that aren't wings in alt mode.
Sentinel Prime - I'm pretty sure his chest is to become the front end of the car. It doesn't.
Animated Deluxe Bumblebee - his chest in robot mode is meant to look like the roof of his alt mode. It isn't. (just pointed out to me by Stompy)

I think it's most pervasive in situations where a toy is meant to match a fictional representation. It's also pervasive in Animated due to the extreme rounded styling of the robot modes.

Is it a cheap tactic?
Does it bother you?
Can you point out any others?
