Kururin Paradise

Paradise vastly improves upon the original game. You can now find hidden keys in the levels, which open up locked doors, allowing for branched paths in the world map. Certain paths also lead to boss encounters, which take the form of addictive mini-games including lawn mowing, gathering stars, flying Kururin himself through clouds, and hopping across a path dodging helicopter blades.

The game features twelve toys built-in that can be accessed by selecting one from a menu, then turning your Game Boy Advance off, then on again. Most of them are fairly useless or incomprehensible in Japanese, but there are a couple of interesting ones, like the love tester, the musical note player, and the memory match game.
