A mermaid tail

Siblings reunite

Blair and Lexie couldn't believe that they were on land and that they have legs now and they went to explore remix city when they saw a familiar face with a group of boys and two babies 

Lexie: Boom is that you 

Boom: wait Blair, Lexie 

Blair and Lexie: Boom 😄😄

And the three hugged 

Babies: 😄😄

Blair: omg human babies look so cute 

Lexie: Blair we

Boom: they know 

Ablaze: who they

Boom: oh guys that's my twin sister Blair and that's my cousin Lexie and girls these are my friends Ablaze, Branch, Hype and Trickee

Blair: and who are these babies 

Hype: this is my son Stone

Stone: 😄 

Branch: and this is my daughter Lumina

Lumina: 😄 

Lexie: how is she yours 

Branch: I adopted her 

Boom: where's Bam 

Meanwhile 

Bam: how is it hard for you to find your sister and cousin

Then he sees a unicycle that someone abandoned 

Bam: *picks it up* I never thought I see it here 

Then he remembers from when he was 5 years old 

15 years ago 

Bam: I'm bored 😑 

Then he sees something fall into the sea (it's a unicycle)

Bam: what's that 😮 

He swims to it 

Olivia: hey Bam *swims to him* 

Bam: hey Livie check out what I found 

Olivia: what is that thing 🤨

Bam: I don't know it looks like one of those things humans make 

Olivia: let's ask dad about this thing

At the castle 

Bam: hey dad check out what I found 

He learned that it was a unicycle and he wanted to ride but was sad that learning how requires having legs since his grandma decided to not let the kids go on land 

Bam: well I guess since I have legs now I can finally learn how 

And he was able to figure it out almost as quickly as he relearned how to walk but he ends up crashing into a girl who was on her skateboard 

Bam: I'm so sorry 😞 

Girl: no you're alright 

Bam: 😳 you're so pretty 

Girl: thanks I don't get that a lot from guys I'm Tracy by the way

Bam: I'm Bam 

Later he saw Boom and he told the three about why he is on land and he was horrified to hear about what happened to Olivia and Cyclone
