There is a lot of stuff going on in this scene and its a very unique pinball game.
The ball is launched into the game by a 2 stage spawn rocket (Its actually a one stage rocket that appears to be 2 stages) and both stages burn up on re-entry of the atmosphere.
There is an alien that when the ball goes into his mouth for points he closes his mouth, then spits the ball out. Also when the ball goes near his hands he hits the ball away.
Theres a UFO that has a tractor beam that is activated when the ball is near and the UFO abducts the ball and tries to drop it between the flippers to make you lose the ball.
When the ball goes between the flippers out of play it make a crater in the Earth.
Theres a black hole that the ball will go into a decaying orbit around before it eats your ball.
Theres more but you will find it when you play the game.
Please rate, thank you.
