The 3rd movie is pointless, and was only made because the first 2 made money. Nothing insulting to the intelligence, so no Last Jedi, but the plot being not really needed, combined to the team being forced to do CG because "that's what the kids are into", turns a harmless sequel into a harmless sequel that looks ugly. The storyboarder basically told people to not watch it (no, don't think I cared enough to save proof he said that, but good old 4chan did post it).
TL;DR of the story: set after the TV show that was also made 4 money (and is also not necessary), Hugo and Rita come back to Denmark EVEN THOUGH IT'S WINTER, some more people try to catch Hugo, in the end the pair ends up in a big nature preserve park think, the end. Oh, and they adopt an abandoned jungle creature, cuz a kids' movie even in Denmark isn't brave enough to openly state "WE CANNOT PROCREATE WOE IS US".
