Christmas with Naneta and Pagachu is a Japanese christmas Anime TV Special developed by Shin-Ei Animation.

Plot
Naneta and Pagachu were taking a vacation from their OVA series for the Christmas but while they were both decorating their Christmas tree for the Christmas celebration, the teleportation device builted by Yumi and Hiroku started to malfunction causing it to sent them from Waku Yaniko Land to Fujiko Fujio Land where they met Chimpui and Kurobe (who is under the disguise of Mr Cat due to still being on the run from The Association to Stop Racism Against Blacks). Naneta both asked them if they can find a way to get her and Pagachu back to Waku Yaniko Land but Kurobe told them that Yumi and Hiroku told Chimpui via telepathy that they are both inventing a machine that can get Pagachu and Naneta back to Waku Yaniko Land so in the meantime, they decided to stay in Fujiko Fujio Land learning that there is more to Christmas than getting presents. When they are finishing helping Kurobe and Chimpui with the decoration, Yumi and Hiroku both told Pagachu via telepathy that they have finished with device that can bring Pagachu and Naneta back to Waku Yaniko Land. Pagachu and Naneta waved goodbye to Chimpui and Kurobe before they got teleported back to Waku Yaniko Land, just in time for the Christmas celebration.
