Hello Kitty Jabba the Hutt Decal by LadiBugXpress
Etsy seller LadiBugXpress has a number of variations on Hello Kitty available as decals. As of this writing, the Jabba one isn’t available on the site anymore, but I would imagine you could get one if you ask. It’s a vinyl decal, and rather large at about 6″ tall by 4.5″ wide. You can get these in a variety of colors, but white seemed like the best choice to me.
I’ve actually tried a couple of times to draw a mashup of Hello Kitty and Jabba and it’s not easy. The Hello Kitty design is deceptively simple, but it can be difficult to get the proportions right, and if you change it too much to get her to look like another character, she will stop looking like Hello Kitty. I think they did a pretty good job, though. Hello Kitty doesn’t normally have a mouth, but I guess they decided that having the tongue coming out was an important part of getting her to look like Jabba. The mouth is a separate piece of vinyl, so you wouldn’t even have to use it if you didn’t want to.
I’m not sure if I’m ready to have Hello Kitty join the Think Geek Star Wars family decals I have on my car, so I put one of the decals on one of the windows in my office.
