His tentacles grasp and snake upwards along the log the further it sinks in. He's using them mostly because if they get trapped he could easily de-summon them since they are mostly a subconscious spell instead of part of his body. They fold upwards near the top and when they become useless, he leans down and pushes the tree in the rest of the way.

It's an odd look and view from up above. Anything in the water usually had some movement but the tree was oddly still. He plays with his bottom lip gently as he examines it. There's a need to want to poke it but he doesn't, favoring instead a candy bon bon from his pocket and letting that drop into the water. The fish seem to be doing that all on their own as well providing him an interesting perspective.

When Strange joins him, his head tilts to the side with his usual grin, "Looks stable."
