Here are some of the other images from that comic. I don't have any more of the girl getting tickled by the machines, by I do have her getting tickled in other ways. I'm hoping there is even MORE, and that someone would be kind enough to upload or link to the images as MY New Official Best Friend Mostly Harmless has done.
By the way, apparently the redhead being tickled is a Dragon Quest 4 character named Alena. Personally, I like this artist's rendition of her better than Akira Toriyama's. I'm a huge fan of DragonBall, DragonBall Z, and DragonBall GT, but I always thought Toriyama drew his female characters a little on the butch side (except Bulma and Launch in the early volumes of DragonBall).
