The more that they moved through the jungle, the more that the party was able to see what the echidnas did for homes. There were many wooden hits made with jungle vines. However, the vines grown had been guided to naturally grow in a way that helped the pieces of wood stay together. It was a unique mix of building and also natural growth.
Furthermore, there were echidnas that were using skills to create things from plants right before the party's eyes. Some were fashioning staffs and bows from vines and other jungle materials, some of which the party had never seen.
'Water gourd
The water gourd is a unique plant that can only grow in the jungles. Just like any vine, it will grow up and around trees to get closer to sunlight. It will absorb water naturally until its flowers grow in to a large gourd. When it is close to the end of its lifespan, the gourd will fall and shatter releasing seeds and water for another vine to grow.
