That is VisualStudio trying to confuse you. It sees the value 0 in the array, and tries to be helpful by translating it to the enum symbol. Unfortunately there are two such symbols both representing zero - biFirstBiome and biOcean. VS just chooses one. So your chunk comprises of ocean only, which seems alright.
The problem with animals vs monsters is in the spawning. The spawning method MCS uses is almost what vanilla uses - it only spawns mobs. The reasoning behind it is that animals get generated within chunks and they don't despawn, so they shouldn't be spawned. Unfortunately MCS doesn't generate animals just yet, so the net result is that you don't get animals.
