Aside from dolliehs I'm a sucker for raptor plushies and plushies of weird shit in general (i.e. insects and other not so cute furry things). I also still have a few of my old Jurassic Park dinos that I'll never give away, and I always feel the need to buy gashapon/trading figures I don't need at cons. Usually Gundam, though occasionally I've bought stuff because it looks cool.
Speaking of I've got some Gunpla and MSiAs on and off since I'm a Gundamtard and that's obligatory. I don't build the Gunpla like I should though so I fail in that respect. Most of it is UC since being a crotchety elitist I don't play nice with Wing/SEED/00.
I may or may not give in one day and buy
this sucker even though knowing me I won't build it and I'd have to track it down on Y!J and pay like 400 bux. It's Ghinius related so it tempts me by default.
