Resource pack based on [Animated Fox Guis by Ekuzen] project. It adds an animated sleeping fox to inventory. In this pack, it replaces the recipe book button
 

Initially did it for myself. Made it work with new 1.20.2+ gui, instead of needing optifine. Because of this there's no fox biome variation. But this "lite version" suits me, especially since now the fox can be added in any Gui resource pack.

It's good to have a friend in your inventory

Vanilla, no optifine needed. works only in 1.20.2+

Great thanks to the author of the original resource pack - Ekuzen
