Game Hunting: Game Boy Pop Up & a Cheap Bayonetta

I was a bit late in hitting up a local swap meet today, but I was quite happy to walk away with some solid finds.  A cheap copy of Lego Star Wars for the Wii, Flying Dragon for the N64 (now in my collection), a loose NES system, and Bayonetta (sealed for $25).  I’m especially happy about the Bayonetta since used copies still seem to be in the $40+ range or more…and it’s going to be a solid game to play.

One of the more unique but probably not really rare games I picked up is for the original Nintendo Game Boy and is called “Pop Up.”  It’s a puzzle game in which you used trampolines or bumpers to navigate a ball through puzzles.  Game play is decent actually, and the background music is fantastic!  I can’t found out much about it online, and I’m wondering what’s it’s worth.  There are a couple on eBay for cheap by European sellers, but none seem to be up for eBay USA.  Just for reference, this one says “DMG-OP-NOE” on one side of the label and “HERAUSRAGENDE SEITE” on the other, so I’m assuming this is a German release.  Interesting find for a San Diego flea market…
