Speed's new nickname is Bambi. (See my post about him being mistaken for a deer.) He's got a couple of other nicknames as well: Mr. Pointy and Torpedo Head.

Of course, if he's Bambi, Sky has to be Thumper. Which fits her anyway because she thumps her tail on the floor when you come into the room while she's lying on her side. :-)

Also, Electra is The Princess, Kismet (Kizzy) is Eeper (she had a high-pitched meow as a kitten, that sounded sort of like "eep"), Bijou is Jelly Baby (she nurses like a baby and has a jelly belly), and River is Foof (she's big and foofy). Elton is Weeble (he wobbles *and* falls down). Freddie and Serena haven't really inspired nicknames, though, which they're probably not unhappy about.

Anyone else here have goofy nicknames for their pets?
