This resource pack imagines what the fins that Striders were once planned to have would be like, (the unused texture for the fin was in the files for a few snapshots after the strider's initial implementation). This is an aesthetic change, and isn't really that useful, but Hey! It existed, so why not bring it back! It is a really simple pack, but does require Optifine to work.
