It's called Lilo &Stitch: The Series.
Lilo & Stitch: The Series has featured four crossover episodes with four other Disney animated series. The first of these was an episode titled "Morpholomew", which aired on July 1, 2005 and featured characters from American Dragon: Jake Long. This was followed by "Spats", which aired on August 12, 2005, and featured a crossover with The Proud Family. The third Lilo & Stitch crossover was in "Rufus", which featured characters from Kim Possible and aired on August 26, 2005. The last Lilo & Stitch crossover was in "Lax", which featured characters from Recess and aired on January 16, 2006. Notably, Recess was the only non-Disney Channel Original Series to cross over with this series, and the only series whose production and broadcast of new episodes had already ended before Lilo & Stitch: The Series debuted.
They were pretty enjoyable.
