From your spawn point, travel north until you are almost at the tunnel, then move east and walk into the second house you find. If done correctly, the "A Goat Amongst Legends" challenge will start. Go up to the second floor, and press R at the television to play "Flappy Goat". This is easier if you do not have any other powers available, or rebinding the "Action" key to something else. Also try knocking the sofa and table out of the way, and zoom in to the television for a better view. Make it past ten obstacles in the mini-game without dying to score 10 points.
Take the wind statue on top of the second windmill (the one in the middle). Then, bring it to the altar located to the left of the skate park. Look for a path with torches to find it.
This achievement is earned after you walk on your front legs for 3,000 Manual points. Start by standing on level ground. Then tap S (move backwards) then W (move forward) in quick succession. If done correctly, your goat will be walking on its front legs. Keep balanced while the Manual points increment. If the balance meter gets too high, press S, and press W if it is too low. You can also press F to enter slow motion to make this easier, however you will spend more time maintaining your balance. To keep the accumulated Manual points for the achievement, you must get back on four legs flawlessly. To do so, press [Jump].
The trophies are found at the following locations.
Enter the bull park next to the bull under the rollercoaster. Someone will jump on your back. Go on top of the hill behind the skate park. Go through the dam and when you exit, the catapult can be found is to your left.
Start a custom game in the Goat City Bay level. Follow the orange car and travel down the road until you see a blue building with large balconies on the right side. After it, on the same side of the road, is a grayish house with a garage. Enter that house and find a pot named "Jack" in a room with red walls on the second floor. Hit, touch, or lick the pot to earn the achievement .
A version of the popular mobile game "Flappy Bird" can be found and played in this game. If you go into the Coffee Stain Studios building near the mountains and head upstairs, you'll see a large TV in one of the back rooms. Attack it and it'll turn on, and it will let you play "Flappy Goat", where the objective is to get your character through as many pipes as possible by pressing R to bounce him up.
