There are 30 golden goat trophies on each map. My video guide shows you all 30 collectibles on the map called "Goat Ville".
All collectibles are saved immediately when picked up. There is a quest for collecting all 30, activate the quest in the pause menu and you can see how many golden goat trophies you have found.
The collectibles video is one long sequence. I collect all 30 golden goat trophies without cuts or getting a new starting point. The order is logical and not criss-cross.
The spoiler contains a timeline with all collectibles.
