Also a Moment Of Awesome when, just before, Reepicheep beats Eustace up with a sword whilst being held upside down by the tail. Reepicheep then chases Eustace around the ship, beating him with the flat of the blade. Oh, yeah: Reepicheep is a TALKING MOUSE. Granted, he's a little bigger than normal, but come on, it's hard to be that Badass while being that size — even Yoda was 2 feet tall.
Even funnier is when Caspian has to threaten to tie Reepicheep up in order to keep him from challenging Dragon Eustace to single combat.
The Dufflepuds, especially when they miss Eustace's snarking at them. Also, almost all of their comments.
