After collecting...
... 1-5 trophies, you´ll unlock the Magical Headbutt Goat,
... 6-10 trophies you´ll unlock the Hogtie Goat,
... 11-15 trophies you`ll unlock the Scale Goat
and finally after collecting 16-20 trophies you`ll unlock the Helicopterkin Goat.

All of them come with unique features and are really fun to play!

I recommend using Valentino Salami to get most of them, because you can fly around and get to most places that are otherwise hard to access.

I hope you enjoy and happy collecting! :)

On top of the cage and spawnpoint of Valentino Salami in the zoo.

On top of the big building next to the ship.

Behind a bush at the tip of the beach near the ship.

Behind a little shack. Go up the street next to the ship, turn right and follow the road and you should see it.

On top of the building with the big sign reading CANDY´S SWEETS and JAY´S PHARMACY. You should see the sign form the little shack.

On top of the 2nd tallest building in the town.

Behind the bar above the cinema, which is also the tallest building.

On top of the casino.

Inside the casino, in the middle of a ring made of Hi Roller slot machines.

On the left oft the Arobics Center (between the casino and the cinema) is a small alleyway which leads to little backyard, turn left and you should see it.

Inside the COWIES´S burger restaurant, behind some cookers behind the bar.

On a grid next to the big sign reading FLAREBUD. You should see it from the burger restaurant.

Inside a cell down in the pit-like prison. If you can´t find it, assault a police officer, he´ll throw you in there :D

On top of the bank, in the corner right above the Baaa Machine next to the musicans.

On a little flying island. From the bank you should see the end of the railroad. From there you should see a cannon up the hill. It faces straight to the island, you can either use it to launch yourself up there, or you can use Valentino Salami to fly, the choice is yours!

In a small room with a named npc at a backyard. Turn right at the Cat Sausage building and you should see some wooden planks next to some graffiti and a trampoline. Break the planks and go inside – the trophy is on the table.

Below the screen with the movie played at the drive-in theatre. You can make yourself comfortable while you're there, or go looking for the last three trophies! ;)

Near the racing area in the trailer park with the tuned cars, behind the long house with a pile of wood on the front.

Take one of the cars and have some fun racing! Follow the track and jump over the ramp, you should land in a little desert area with a destroyed car in front of a tall rock. The trophy is on top of this rock.

At the end of a wooden dock at a lake. Just follow the racing track and you should see it. That's it, that was the last one! Congrats and have fun with the new mutators ;)
