Look for a rock wall on the northern side, and head through.
You will eventually come to the area where the Bubbulfrog is located.

Destroy the rocks and then head inside to fight some skeleton enemies.
With those defeated, look around the room.
You will see a gate, which you cannot get past.
There’s a small alcove opposite, with a rock that can be moved using Ultrahand.
Do this, and then jump down the hole.
Head to the end of this tunnel and then useAscend.
You will find yourself on the other side of the gate from earlier.
