this one is beyond me.

The classic from the 70s, which I think this is probably based on, is David West's Bubblegum. I have a digital version of it, and I'll try to track down the source.
You could also try the newer Magical Mystery Tour (#19, a free download), or Wubble.

Fellow Stockholm typophile Göran Söderström also did a lovely font in the same vein called Autostyler, which is available on request.
House Industries Poolhouse is similar too.
