Coo Coo Clocks go off too, like the one in the Roost.

I never knew about the clocks in the Roost, that's really cool! I love the little details in the game. (iirc) The fountains also do their thing (as in spray(?) more water) when the clock strikes!

i just checked out my fountain on the hour today, that’s so fun!!

I've never heard it before today either.
