Don't know if this imageset has an actual name. First two had "backdoor" in the title so this is what I cameup with

>Don't know if this imageset has an actual name

There is no 'actual' name.
This is a collection of 4 (or 3) different subsets: images 1-2; 3-4; 5; 6 (5-6?).
While thouse all are thematically connected, and can be placed in a loose continuity together, strictly speaking thouse are just three (or four) different commissions made by Sparrow during a relatively lengthy period of time, afaik.
"Stitch's Backdoor Shenanigans" serves just as well as anything else, to think.

Good to know!
While the continuity might be loose, I'd say it's definitely intentional. The door with tally marks on it in the first two images has been broken from overuse in the third and fourth.

It's funny that Jasmine was actually seduced by Stitch in an official teaser trailer for the movie but she is one of the only brown girls not in his Sparrow harem at the moment. XD
