...So, while working on the animals, I decided to change things for the domestic ones.
-All normal domestic animals are gone.
-Cats are replaced with the rainbow ocelots and dogs are replaced with rainbow worgs.
-Horses and other hooved animals are replaced with the lesser ponies.
[they all existed previously, but didn't replace the vanilla creatures]
-Birds are replaced with an egg-laying beetle.
-Also a milkable giant maggot.
Lesser pony creature altered significantly. Castes are now:
-'Normal' lesser ponies were enlarged. They are now the only wagon-puller and pack animal. NOT useful for the rainbow factory.
-Fluffy ponies were shrunk. They are the only spectra source apart from slain enemies. Spectra can be refined from the nervous tissue, or from the shorn wool (less effective, but keeps the ponies alive).
-Breaker ponies - the tainted version. Large and armored, with an additional shell around the body and a head-plate. These are trainable.
Bee evolution [kinda sounds like a SyFy Original Movie title...]
-Bumblebees have been upgraded to Bloatbees, honey bees to Felfire Bees
-Both have a somewhat more severe sting syndrome
-Felfire bees have honey with MV 5 and jelly with MV 3, Bloatbees have this reversed
-Wax MV increased to 3 to make wax crafting somewhat worthwhile
-Reactions to make two decorative bio-metals and a synthetic gem from wax and mushrooms
[UPD] Oh, and: to further increase the value of bees, I've made custom reaction for brewing mead. You can brew a full barrel (15 drink units, 3 honey) or a full pot (30 drink units, 6 honey) from either kind of honey. Om nom nom.
