The Guardians of the Beam - The Turtle

The Turtle, an important one of the Guardians of the Beam, sits opposite the Bear.  Is this the same Turtle mentioned in IT?  Some people say it is, some say it isn't, you decide...

"See the TURTLE of enormous girth,
On his shell he holds the earth.
If you want to run and play,
Come along the BEAM today."
(Seen by Jake at the Lot with the Rose)

"See the TURTLE of enormous girth!
On his shell he holds the earth.
His thought is slow but always kind;
He holds us all within his mind.
On his back all vows are made;
He sees the truth but mayn't aid.
He loves the land and loves the sea,
And even loves a child like me."
(As told by Roland)
