Red Planet 5-20 is the 20th level in Red Planet. This level is one of the tough level.
Launch Terence towards the rightmost stone sphere on the “satellite”. You want to push that structure far enough into the steam geysers. From there, you can expect the blocks to be bounced up and down long enough to detonate the left tnt. The debris from that explosion should destroy the blue crystal, and the pigs. Use a second bird to destroy the remaining pig, usually located at the bottom left.
