Chomper's at the same tree that Cera's at, so imagine there's only one tree. However, I did envision this tree as something of a skinny, tall sapling, but apparently one triceratops, one tyranosaurus, and one oviraptor are incapable of dislodging it from the ground, leading me to believe that said sappling's roots strech down deep enough to tickle the top of the earth's mantle, or this tree is made of wooden wolverine claws.
So basically, how big is this tree that's getting pushed down?
