"The Rules" is a song from the episode "Monster Detectives".
Tyrone: You must be sneaky now!
Uniqua: I must be sneaky now!
Tyrone: Especially sneaky now!
Uniqua: Especially sneaky now!
Tyrone: You can’t have shoes that are squeaky now, lady. You gotta be quiet, too!
Uniqua: Quiet, too!
Tyrone: Quiet, too...rule number one: be quiet. You cannot make a sound! Make sure your feet land softly when they step upon the ground!
Uniqua: Okay, I must be quiet! I will not make a sound! But what if I must yell or shriek or howl like a hound?
Tyrone: You mustn’t even make a peep, or else we will be found. Pay attention, lady, 'cause here’s rule number two: if you see that monster, do not let it play with you! If you play with the monster, lady, you’ll be through! ‘Cause whoever plays with the monster will become a monster, too!
Uniqua: If I play with that monster, I’ll be a monster, too! Hey, that might be pretty neat! It might be fun to do!
Tyrone: No that won’t be neat! It’s not what you should do! So, if you see that monster, do not let it play with you! We’ll creep and sneak to peek around 'til we find that soccer ball...
Uniqua: Soccer ball...
Both: 'Til we find that soccer ball!
