All of the dragons from http://flightrising.com/main.php?p=lair&id=74903&tab=dragon&did=32882228 to the end of my lair I'm willing to trade for any combination of 4 green ooze and/or green sludge. You are free to flip, exalt or make them cherished parts of your lair. Send a CR and, assuming I see it before they sell I'll be delighted to accept. Includes some tree and koi dragons.
