When I was 8, my brother made me watch Terminator 2, and I had nightmares for weeks about waking up, walking into my kitchen, and finding my mother with her arm transformed into a blade, with which she would be slaughtering my dad. It's nice to know that small Japanese children may be able to share my childhood dreams.
...Seriously though. WTF? Whose idea was this? And who heard the idea and thought “man, we should totally make that happen”? Maybe it's a really brilliant move, a play for the longer game: make sure that the Terminator is cool when the kids are young, so they'll go see sneak in to see an R-equivalent-rated Terminator 13 when they're older. Or maybe it's just targeted at Doraemon-watchers' parents. Either way, I hope to god someone puts a clip on YouTube.
