Tangle trees are a dangerous type of tree found in Xanth.
Tangle trees are famous for their predatory nature. Their name comes from how their tentacle-like branches are able to quickly grab any prey that comes too close, pulling them in until it is able to begin consuming them. They can grow to considerable size and will clear out the area around them of rocks, branches, and debris to make the landscape appear more inviting to passers-by. Refuse gets tossed into a circle just outside of their reach. Over time, the land will slowly begin to grow over the refuse, forming a rim of sorts. Many adult tanglers will appear to be in a natural well.
