Part II: More changes to our Life
A continuation of the previous episode. In it, the Loud siblings make a description of how it will be the life with some changes.
The episode starts where the previous ended. This time is turn of the other 5 siblings to tell their changes of the life.
The thing that Luna apports to the family is being more 'rockers'. In her change, all listen music only from Mick Swagger, but her siblings don't like too much his music. The things became bad when Luna starts to play Mick all time.
Lori has a small change. In this case, her illusions of a family change is when their parents are gone, all her siblings do whatever she says. But Lori goes to the extremes when she's abusing of her authority.
Lisa has a change that involves in all being smart as her level. At first it goes ok, but later, all the siblings start to having a higher IQ than her, even Lily who had learned to speak 3 different languages in 3 weeks!
Lucy changes the entire house to black, and makes her siblings, spooky costumes and teaches how not to speak properly. She also teaches her siblings poetry, but she quits when Lincoln is better than her.
Lola's change involves Lana on being more femenine (the opposite of the previous episode). All starts with Lola having a tea party with Lana, but the others also want to join. Lola is surprised, because all the others thinks that tea parties is useless.
Almost the outro.
When Lola finished her story, all are confused each other, because they don't know that changes each one had. The siblings start to talk each other, until Lily comes. The baby 'tells' a story in which her siblings were a little smaller, and played with her.
