Got the batty bush gold star. I'm starting to think that Monsters University has a bug where you may randomly not unlike any given gold star mission. I've heard several missions that didn't award the Gold Star when completed.
I just bought the pool an watched it drain but the gate to the pool area is still closed...
Edit: Saved and reloaded. Got the challenges over there. Now my Clothe make the Monster is the last one. Ever figure that out @Explicit? I swear I did this once during the gameplay missions.
Does anyone recall if a Monsters University sky was given in the play set? I know the Incredibles have one that can be used in toy box mode, but did MU have one? I don't recall ever receiving one.
