Origami Advent Calendar - Foxes

This is one of my favorite Advent Calendars I've made so far. It is full of foxes: the animals and the boxes. The fox boxes have small surprises with different flavors. The foxes with 4 legs (or in this case without any legs, but with cute tail) are paired with fishes. 

Since the Calendar is used during the Christmas fasting period, I found an easy way to represent the fish-allowed days. Can you guess which are them?
