Koala Jigsaw Puzzle
The koala is a cute marsupial native to Australia. To see him in his favorite eucalyptus tree, you have to complete the jigsaw puzzle.
To turn a jigsaw piece over, hold the "T" key and left-click your mouse. Also keep in mind that pieces can hide behind each other, so move the pieces (or your partially completed puzzle) around the board to see what's underneath.
