Hello Thistle, I just checked this in a test game. I dragged and dropped it from the compendium onto a map. It has the Tentacles attack listed. Can you provide us a screenshot of what you see? What character sheet are you using? Additionally, to rule out potential issues, please carefully work through these steps of our guide to Solving Technical Issues .
