Ok because nobody found out what it means I'll give some hints:
-ESCATOC is made out of 3 common abbreviations.
-2nd and 3rd are already guessed right by some people.
- for the 1st one: the colours on the left of the adoptables (with "ESCATOC" over them) may help you
That's all. And you have a week to find out, and still the firts person, who guesses right gets one of them for free. Everyone can guess 3 times.
