I guess they did something like "brown bear, brown bear", but it was "children, children". Oren was the fire-breathing dragon, and Mark said he breathed very well. Not having been there, I don't know what all the pictures were. I would guess the top is him being a dragon. The middle 2 are probably a little group recitation (they did something similar for an earlier musical performance) and I think the bottom one is sharing a memory from his "memory book". They have been working on those all year.
