One of Doctor Trickles experiments failed and created little creatures spreading more and more all over the world. Now you must step in and stop them before they overwhelm the whole planet. Combine 4 or more Trickles to destroy them. The more you combine the more points you will get. Good luck!
Use LEFT and RIGHT ARROW KEYS to adjust the position, press UP ARROW KEY to rotate Trickles and use DOWN ARROW KEY to drop the Trickles down.
