The goal is to make the mobs more dynamic and believable. It gives an animation overhaul to the creatures in the default look of Minecraft. Within a few months, the pack had already received several hundred thousand downloads.
The project was published at the end of 2020 and is a work-in-progress pack, which means that it is developed over time and is not fully finished. The project was a success right from the beginning since it was a completely new mod idea. This is not a bad thing at all because the new animations for the Minecraft mobs are exceptional. FreshAlex, the creator from New Zealand, focused solely on mobs and did not change any blocks or items.
However, you do not have to search for a long time in Minecraft because a single glance at the mobs should be sufficient. Initially, it may not be immediately apparent what changes the Fresh Animations texture pack makes.
