Goat Simulator

Basically it's the only online achievement in this game that requires your friend and you be in-game in order to get this achievement. (Just have in mind that you have to be friends in steam in order to get this achievement, otherwise it won't work.)

Once you're in-game with friend in same map (MMO) you can find your friend either on spawnpoint, or in city (Goatwind). Just use "Lick button" by default it is "E" button. You'll get instantly after licking your friend NPC.

Basically for all of thoe achievements you can use either video guides or maps (with each location of tropies on it)

Or you can just simply download the mod (in official steam workshop for goat simulator), which makes trophies larger to see (P.S. this doesn't make hitboxes larger than they were originally) and marks every spot by numbers (to pick them up just go precisely to point where numbers are located).

Those 2 methods work both video guide and mod one.
