8) Splatoon
Before writing this off, remember that Nintendo has been both praised and mocked for being a company that essentially makes toys for kids, moreso than their distinguished competition. Splatoon is easily their most kid-friendly property right now, and has an easy hook: make a mess to win the game. Making a mess is an easy sell to anyone under the age of say, seven or eight, and it allows Nintendo to have a musical that rivals The Wiggles, which cleans up with kids.
All you’d need is some music that straddles the line between weirdly catchy and annoyingly persistent in your head, some lights, and squid costumes that put Left Shark to shame. Once all those are in place, you’ve got a show kids won’t shut up about until they force their parents to see it over and over again.
