Don't be scared -- Those things you see are just awesome Bendy obstacles :)
They are unique -- You won't find them anywhere outside the Flapworld!
Try to collect life forms when maneuvering swiftly through the pipes, maybe you get lucky and snatch a special Booster life form! Boosters are rare but very helpful and can increase the length of your flight dramatically, use them wisely!
Be the best Flapping Bird in Flapworld and rank number One on our LeaderBoard. When you get really good, maybe you are ready to compete in the Platinum ladder?
Good luck and most importantly Enjoy! :)
