Stitch made a comeback in a newer series that at first I was very, very skeptical about. It's very different, and my favorite characters are not in the show hardly at all. Also, there are both old and new experiments and perhaps the biggest difference is the location is no longer in Hawaii.
Surprisingly, this is not a Disney show. It's a company in Japan that made a half-cartoon, half-anime series. A lot of the newer characters are anime like but some are more like the original designs. Also, Lilo herself is AN ADULT in this show in one of the very last episodes. That was surprising to see.
Anyway, Stitch himself sneezes at least 3 seperate times in three different episodes. Also, there's an episode where Stitch gets shrunk and some girl does too. MICRO CAUSING SNEEZE against a cat that tries to attack both the girl and Stitch. Actually a really nicely done scene. There's also sneezes from a few of the human characters as well.
Anyway, if anyone is interested I can find the exact times the sneezes happen where Stitch sneezes
