The difficulty here is making the toaster astonished, making it look astonished shouldn’t be an issue, however the cause of said astonishment is a mite troublesome.
Idea 1: The toaster is new, comes out of it’s box and as such has never functioned as a toaster, and therefore doesn’t know it’s raison d’etre.
Opening scene, toaster comes out of the box, shall be tricky to animate hands and fiddly geometry. Gets plugged in (off camera) and has bread inserted.
Scene 2, toast reacts wildly to having bread inserted. I’m thinking some sort of rodeo, bucking bull display obviously hampered by the fact it’s plugged in.
Scene 3, after much struggling the toast pops up and out. Astonished, I want the toaster to examine and sniff it like a curious puppy, then (although i’m unsure how to resolve this) the toaster realises it’s purposes and settles down.
Let me know what you think, I believe this idea is pretty strong, but am acutely aware that it is (like all my best ones) the first out of my head.
