Mickey Mouse: Okay, Dijon. (to Pluto) Alright, Pluto. Smell them out.
Pluto: (smells Arthur and Cecil out) Bark! Bark!
So, The group heads out on the search and rescue.
Rarity: Good luck.
Meanwhile, Arthur and Cecil had to keep watch on Emerald until Klang and McGraws' return.
Arthur: Well, This is boring. How long do you think Klang gets back?
Cecil: Beats me, Artie. What else could go wrong?
Baby Emerald: (made a sad face)
Arthur: I think you spoke too soon, Cecil.
Cecil: Uh Oh.
Baby Emerald: (crying)
Arthur: Oh, Don't cry. We didn't mean to take you away from your mother. What'll we do now, Cec?
Cecil: Hey, Arthur. What kind of book did you took just before we snatched the baby?
Arthur: I don't know, Cec. Wait a minute! (checked the bag and found the "Baby's Day Out" book) Here it is. Baby's Day Out. That's just the medicine for a baby pony.
Baby Emerald: (stopped crying and cheering up)
Arthur: Yeah, You like that, Don't ya?
Cecil: Come on, Artie. Get to it!
So, Arthur and Cecil started reading Baby's Day Out to Emerald.
Baby Emerald: (happy gurgling)
Arthur: (reads) "Nanny and Baby Boo strolled through the great big department store."
Cecil: (reads) "How many, many things there were to buy."
After reading the book, Arthur and Cecil fell asleep.
