In Jurassic Bark, when it shows Fry going to the Applied Cryogenics place, as he sets the pizza on the table you can see Nibbler's third - eye stalk poking out of the trash can. Later, you can also see a shadow as he's falling backward - probably the shadows of himself and Nibbler under the desk.
Am I crazy? Or did anyone else see it too?
I think it's a very established fact, that yes, what you saw is correct. Seen "The Why of Fry" yet? You'll get the idea why the extra shadow are there.
Also, this entirely hard to find any information on:http://theinfosphere.org/Jurassic_Bark#Continuity
