What is the font used for the lettering in Lite Brite on this box? The font doesn't have to be in rainbow, just the right shapes or as close as possible. Thanks in advance.

Bumping because I'd like to know too. Also submitting this picture for consideration: https://i.imgur.com/ci3Ygsd.jpg

I'm not at all concerned with the drawn in talk texture. What I'm looking for is a font with this overall rounded, almost schoollike shape with lowercase letters available. Apostrophe, comma, and dash are a plus but I can make do without them. I'm sure there's a font out there like this but I just haven't been exposed to enough or simply can't remember ones that have the rounded look of this font.
