Nite time potty

We have been done wearing pull-ups for weeks now. And Gavin is doing so great about it. Gavin also doesnt wear them at night. About 1030 every night I gently get him out of bed and go potty. Usually he only half way wakes up and doesnt say or do much. For the past two nights he has been talking in his half sleep. Sunday night he told me "Froggies dance loud." I have no idea what that means. And last night when I picked him up he told me, " I dont wanna throw the ball. I wanna sing." those are the only words he said.
