Panda, giraffe, hippo, elephant, crocodile, lion, rabbit and monkey magic

If "Zoo Keeper" was a person, I’d wanna give them a great big hug. As it's a Nintendo DS cart, I'll settle for a metaphorical embrace.

A puzzler of the genus "Bejeweled", "Z/K" involves switching the positions of cute animal heads on an 8x8 grid in order to form identical lines of three or more. These then disappear and critters fall from the top of the screen to fill the abhorrent vacuum. (Ideally, triggering a chain reaction.) Play continues until you capture a set amount of animals and progress to the next level, or else the time limit expires, it's game over and you weep blood while screaming white noise.

OK, that last part was an exaggeration.

Anyhoo, I tried each of the modes once, hated the guts of "Quest" and took an immediate shine to "Tokoton 100", in which you've gotta bag 100 of any beast to complete each stage. After three games (they take about half an hour!), my highest score's 707,960 (level 20).

According to the wikipedia.org entry, that's the final stage and is followed by a story about the keeper. If only I could have captured a few extra monkeys!
