The Malaysian animated series Upin & Ipin is wildly popular in Indonesia to the extent where SpongeBob SquarePants looks obscure, with (often bootleg) merchandises being sold all over the place. This is partly due to most of the Malaysian language sounding hilarious in Indonesian. Noteworthy because prior to its introduction, Indonesians hated the living shit out of Malaysia and everything in it for "stealing" their culture.
It was kind of ironic, because it was actually an Indonesian who made said cartoon. When it aired for the first time, the reception was bad, so they had to cancel the show. Afterwards, Malaysia bought the copyright, and it became said popular franchise in Indonesia.
