because of sheer unexpected resemblance to a pac-man ghost:
a dumbo octopus.
edit: OK OK, a dumbo octopus with laser beams!
I have an irrational fear of octopuses. Seriously, what other 5-foot long animal can squeeze through an inch long opening? They can also crawl out of water and onto land for brief periods of time, and they are more intelligent than the average 3-year-old. Crazy.
Anyway, back on subject, I would like a zebra. I've always wanted one because I have horses, so a zebra seemed like the next logical step.
Possibly a (male) narwhal, just because their horns are awesome. I would enjoy riding on it and having jousting matches! Never mind the below freezing water...
Another one I'd like is a coconut crab. Essentially, they're giant hermit crabs. Absolutely massive, they have a 3-foot leg span. Locals use them to guard their coconut groves, and yes they can take your fingers off. ...and they taste like lobster
There's a pet store near my house that sells baby giant tortoises. I hate it- I googled the species and they're actually endangered. On top of that, there are two or three of them in a ten-gallon tank. The species in question also lives 150 years and requires super-specialized care, which needless to say is not met by a tiny tank with a heat lamp.
