In that game, you have to whack the beast poping out of the holes to get points. For that purpose, target with the mouse pointer and whack with the space bar. The yellow beasts bring 3 points, the green ones 2 and the red ones 1. Your objective is to get 50 points within 30 seconds. But take care! Sporadically, a frog and a jujube (small red hair ball) will also pop up, and if you hit them, you will loose 5 points! Ready for it? Go...
