Utopia 4-5 is the fifth level of Utopia.
It's not too difficult with strong birds.
Bounce Terence through the two lollipops on the left side of the level, causing him to bounce into the asteroid in the north. The TNT on the northern planet should detonate, along with a lot of popcorn, clearing most of the top half of the level. Fire the other Terence through the bubbled pig and into the wooden structure on the southern planet to finish off the level. Alternatively, you can switch these two shots.
