Knock! Knock!

Knock! Knock!

Joe was expecting a visitor. He was waiting for his friend Harry.

Knock! knock! Joe shot up and opened the door, but it wasn't Harry. It was. . .

. . . a POLAR BEAR! His iceberg had melted, so Joe gave him an ice lolly and send him on his way.

Joe went back to wait for Harry. Knock! Knock! Joe jumped up and opened the door, but it wasn't Harry. It was. . .

. . . an ALIEN! His spaceship had run out of fuel and had crash-landed on the front lawn.
