I initailly started writing for an issue that isn't actually this mods fault, but as I've already written everything else out I may as well post it.

I loaded a minimal instance with just Hybrid Aquatic, Kotlinforforge, and geckolib, and noticed three groups of errors.

1. "[Worker-Main-15/WARN] [minecraft/BlockStateModelLoader]: Exception loading blockstate definition: 'hybrid-aquatic:blockstates/anemone.json' missing model for variant: 'hybrid-aquatic:anemone#face=ceiling,facing=north,waterlogged=true'"
   This error occurs 24 times for each of the three anemone types.

2. "[Worker-Main-15/WARN] [minecraft/ModelBakery]: Unable to load model: 'hybrid-aquatic:geo/buoy.geo' referenced from: hybrid-aquatic:geo/buoy.geo: java.io.FileNotFoundException: hybrid-aquatic:models/geo/buoy.geo.json"
   This error only occurs once as the text above.

3. "[Worker-Main-15/WARN] [minecraft/ModelManager]: Missing textures in model hybrid-aquatic:great_white_shark_plushie#powered=false,rotation=2:"
   This warning occurs with all 8 plushies.

These warnings don't appear to have any negative gameplay effect but thought they were worth bringing up anyways.
