With ostriches, meerkats and vultures making their way into Minecraft, it would be fun to have an Aztec Mythology mashup pack added to Bedrock Edition in exchange, and the newly revealed update offers a perfect chance for this.
We know that in the mythology series are Greek Mythology, Chinese Mythology, Norse Mythology and Egyptian Mythology mashup packs. The Aztec Mythology mashup pack could be a mashup pack based on Aztec Mythology with a whole map of Mythical Mesoamerican Realm, polar bears retextured into tapirs, sea turtles retextured into crocodiles, rabbits retextured into monkeys, silverfishes retextured into rattlesnakes, parity in terms of texture style with Norse Mythology and Egyptian Mythology mashups and a whole original soundtrack composed by Gareth Coker.
Now, there are no new mashups, but there is a mashup pack based on an iconic franchise: the Ice Age mashup pack! Having a mashup pack based on Aztec Mythology would be a fun little surprise for mythology, mashup pack and Bedrock Edition fans.
I suppose there could instead be a sea turtle as itself, but a crocodile tends to be a little more suitable.
