They're quite overpowered but I don't use them. This biome in general is busted, the special rainbow wood has 180% opening speed for doors (basic wood has 120% for reference). Unicorns have 220% caravan riding speed, they also together with the bunnies yield heavy fur. The pink crystals can be destroyed for pink crystal which is extremely valuable and can be farmed by breeding the crystal crabs. The only downsides to this biome are that all animals have 100% revenge and tame chance so not manually hunting is very risky, especially unicorns will fuck you up. There is also periodically a rainbow event where for a period there is a chance of animals and pawns going berserk.
