Rain World

You need to hibernate 10 times. You can use the same hibernation spot over and over if needed, but what I did was go back and forth between the first 2. You need to have full health, so at least 3 if you are the yellow cat slug. Eat fruit, eat bugs, etc. then hibernate. Rinse and repeat and avoid dying. You need to fill up the bar to get to the symbol shown in the image after 5 hibernations, and then 5 more that goes across. Once it shows 'Passage' in the bottom left, the achievement should pop.

I'll update the screen shot with a TA version once the sites decides to pick up my screenshots.
