Straw Vines

Guys, I think it's time to introduce a new vine variant. With only swamp oaks and jungle trees having vines, trees get a bit boring.

So what about straw vines? These vines grow on trees in dry biomes like on oaks in wooded badlands or on acacias in savannas. Their appearance isn't green at all like in the jungle, they look dry and brownish-yellowish - a bit like straw (therefore it's called straw vines).

Straw vines are often hanging down to the surface, so it's easy to climb to the top of an acacia. 

I think this would make trees look more beautiful and decorative.
