I believe that around the 1960s they started to create GMOs, genetically modified offspring (Dont know that much). Maxwell, hearing this, decided to create a creature that was a mixture of human and pine.
Yeah, right? What if the Treeguards are actually like the Rock Lobsters, but instead of having a rock shell, they have a leafy protection? They're actually kinda similiar when compared. Both of them hide from the Player, and only come up when he attacks them. It's funny to think about it.
That's exactly what I said, anon. They're STRONG, but they're also easy to kill; kiting them is fairly easy, but it might take a while, thanks to the high amount of health it has. We'er not implying they're O.P. or anything.
