Meet the Robinsons (2007) More at IMDbPro »

Lewis' peanut butter and jelly machine accidentally shoots just that all over a couple that's interested in adopting him. The man then has an allergic reaction to the peanut butter and the woman must inject a syringe into his leg to stop that (played lightly rather than realistically).

None, but we see a written array of symbols used to denote a curse word (we don't know what word it is).

The Robinsons raise a toast (as does Lewis), but they pour the unknown liquid on their own heads and faces. Several frogs are sen drinking in a bar.

We see a flying bowler hat that then has metal, crab-like legs come out from the bottom (that might be unsettling or scary for younger viewers, especially as the hat -- "Doris" -- sabotages Lewis' invention).

T-Rex-like dinosaur is trying to catch Lewis, and at some point he is inside the jaws.
