UFO Joe is a game from Miniclip on Poptropica that you can play in the Daily Pop in the Games section.
You play as the extraterrestrial Joe. In the game your mission is to abduct alien species, (which can range from regular creatures such as farm animals to actual aliens) and bring them to the local zoo. The controls are on your keyboard: Space- Abduction Beam, the arrows are top(main thrusters); left arrow (fly left); right arrow (fly right), S- Sound (on/off), P- Pause. In the game you have three levels: Earth (medium gravity), the Moon (low gravity), and the unknown planet (high gravity). So there are 15 levels in all, 5 in each stop. When you start a new level, you need to collect the animals by using the abduction beam, and by doing that you will get more points. And try not to bump into any objects. And land on the platform thats blinking in many bright colors. Like most Daily Pop games, you can try to beat other Poptropicans' high scores, which you can see on the bar to the right of the screen.
