In this episode, Q needs U to quiet It.
U is being chased by Q and bumps into I and T.
Suddenly, the ground shakes. "Iet, did you hear that?" asks Q. U doesn't understand. Q sticks with him and says, "I said qu-quiet! Did you hear that?" I thinks It is something big. U thinks it's unbelievably heavy. T thinks it's... tiny, when they see a red It. Then It says U's sound. U asks it to stop. Q agrees and sticks with U again. I and T leave and the other Alphablocks come.
Suddenly, It becomes a duck and starts to quack.
It becomes a parrot and starts to squawk.
It turns into a mouse and starts to squeak. When I and T come back, I finds It annoying. Then U gets Q to hold It, and tries a word without Q...
It doesn't work. U decides to stick with Q.
It goes back to its normal form and goes to sleep.
