Flying trees are the second most common species of trees (after spider trees, of course). They can fly, not because they have wings, but because they can fly. That is why they have wings. What they end up as soon when they retire and shed the wings.
Their wings are the fact that they can fly. See the tree? See it fly? It has wings. That makes it fly. The tree with wings, it flies, when it has flying wings on trees above the flies and winging treeness.
In conclusion, don't do drugs.
(Or else the trees will begin to fly and mop the floor with you! Then Chuck Norris will mop the floor with you! Then your arms will be replaced by flippers and you will not be able to speak!)
The most commons species of the flying tree, the recneps, still remain today. They can be found up in the sky at night. If you look carefully for about 10 hours, you will easily find the recneps flying tree. The recneps species is extremely smart, they have the brains of 10 humans and the strength of 500 tigers. The recneps has a gigantic wenis and the female species has a tiny pagina. Therefore, it is extremely hard to reproduce. This is why the recneps likes to reproduce with other species, such as the Noj. Once the recnoj is created it comes with extremely gigantic wings. The recnoj is also extremely rare.
