It's a game for kids, despite the name, and comes in the nice 3-monitor cab below.
It's another variation of the wack-a-mole gameplay,
where you have to squash the various enemies (mostly evil winged animals) and keep them away from the princess.
This is done by banging a plastic hammer on the two table-top monitors, which are actually touch screens.
Neither year nor manufacturer is shown on screen but, based on a sticker on the PCB, the game must have come out around 1996.
Below is how MAME actually displays the 3 screens when using a single window:
Each touch screen reports in some multiplexed bits which row and column is being hit.
In two players mode each player uses one monitor and hammer. While in single player both monitors must be used, either exploting one or both hammers.
Game's rather short though, consisting of just three different stages.
Hardware-wise, it runs on 1st-gen Cave hardware, with one tilemap chip and one sprite chip for each screen (it's
the first game in the driver to use more than one sprite chip). Note that currently the background scrolling of the right monitor is
a bit off (2nd stage, single player only).
