Slime Rancher

Tabby slimes are the grey slimes with cat ears found fairly close to your ranch down the first main path a little bit, simply let one jump directly towards you and hit you face on. I did this with a Pink Tabby Largos, so i cannot confirm if it has to be a largos or if the normal tabbys work aswell, but both are quite common in the starting area.

Edit: confirmation that it works with the normal tabby slime, so we can safely assume anything tabby works, thanks LEEALEE777

Tabby slimes are the gray cat looking slimes that can appear in most biomes. Periodically, they will hunker down, wiggle their butts, and jump in a direction. If that direction happens to be towards you, they'll boop you right on the nose!

Here's my video for every achievement if you'd prefer. Skip to 1:00 for Boop!

Hey guys, here is a video guide for this achievement. If you are still unsure about anything please message me.

Also as stated by the other guide the tabby slime can just jump at you and you will unlock the achievement but i forgot to say that in the video.

Thanks
