Snakes climb pretty easily. So do snails. The Blob from the movie climbed walls to get the drop on its prey. Oozes also typically strike with a pseudopod.This conversation reminded me of something. In 4e, my Wizard had a utility spell I was rather fond of called Force Ladder. It conjured a ladder made of magical energy. I was always using it in strange ways, like as a bridge for example.
One time we were fighting an ooze that, when struck, spawned tiny ooze minions, so I said ok, I set my ladder against the wall and climb it, and I'll sit on top of it, with my back to the wall. The ladder couldn't fall over, so I figured that was a safe bet.
The DM is like, well, the oozelings climb up the ladder. "How, they have no legs, do they have a climb speed?"
And his response was, "the rules don't say creatures without limbs can't climb".
Also oozes (other than the g cube) have climb speed.
