After Tai reunites with Agumon after he and the team are asleep in a lonely farm, Tai and Yugo are at Alibert's house due to Alibert cannot bake bread all by himself.
"Hey dad, we are back." said Yugo as he returns home.
"Hey Yugo, hey Tai, who is this little fella." said Alibert.
"That's Treasuremon." said Yugo as he introduces Treasuremon to Alibert.
"Wait, I didn't know you have a Digimon partner." said Alibert as he confused how Yugo and Treasuremon became partners.
"Mmm-hmm." said Yugo.
"Also, I hate it when I can't bake bread, can you help me son." said Alibert.
"Sure thing dad, see ya everyone." said Yugo as he is going out when he helps Alibert.
"Bye Yugo, see you later." said Tai, Agumon, and Treasuremon as they wave bye to Yugo.
As Yugo goes out to help his adoptive father Alibert, Tai and Agumon told Treasuremon to stay here in Yugo's room until the window is left open.
"Treasuremon, stay in Yugo's room." said Tai.
"But why." said Treasuremon.
"Because we are afraid that you get lost, okay." said Agumon.
"Okay..." said Treasuremon.
Suddenly, the doorbell rings and Alibert calls Tai and Agumon to open the door for a person.
"Tai, Agumon, can you open the door." said Alibert.
"Here we come, let's go Agumon." said Tai as he and Agumon goes to open the door.
When Tai and Agumon are downstairs to open the door, Treasuremon sees the window left open, causing him to jump himself out. At downstairs, Tai and Agumon opens the door, the person who ranged the doorbell is revealed to be Diane Aillet, a eleven-year old girl with blonde long hair with twintails and no hair ties and a friend of Yugo.
"Hi Tai, thank goodness you were okay." said Diane as she reunites with Tai.
"Hey Diane, thanks, your friend Yugo and a girl named Evangelyne rescued me yesterday." said Tai as he reunites with Diane.
"Hey Agumon." said Diane as she pets Agumon.
"Hi Diane." said Agumon.
"What's that smell." said Diane.
As Diane smells some bread, Tai went upstairs to look for Treasuremon, causing him to gasp.
"Ohh, bread." said Diane as she wants to eat bread.
"Diane, no, you can't eat these." said Alibert.
"But why Alibert." said Diane.
"I'm not a good bread maker." said Alibert.
Suddenly, Diane and Alibert hears Tai screaming when he discovered that Treasuremon went missing in Yugo's room, Diane and Agumon went upstairs to look for Treasuremon.
"Treasuremon, where are you!" said Tai in shock.
"Treasuremon, who's Treasuremon." said Diane.
"Yugo's Digimon partner, he got lost." said Tai in shock.
"It looks like Yugo forgot to close the window." said Diane.
"Yugo is going out to help his father Alibert." said Agumon.
"Oh, okay." said Diane.
"Let's go and find Treasuremon." said Tai in shock.
"Agumon, stay here." said Diane.
As Agumon stays here in Yugo's house, Tai and Diane went outside to look for Treasuremon.
"Treasuremon!" shouts Tai.
"Treasuremon!" shouts Diane.
"Treasuremon!" shouts Tai.
"Treasuremon! Where are you little fella!" shouts Diane.
"We tried to look for him, but failed." said Tai.
"I'll look for him, you sit here in the bench." said Diane.
"Okay Diane." said Tai as he sits in the bench.
As Tai sits in the bench, Diane runs and looks for Treasuremon. Minutes later, as Tai is humming the Digimon Adventure theme song, Diane screams and calls Tai after finding Treasuremon.
"TAI, THE CAT ATE TREASUREMON!" screams Diane.
"Huh!" said Tai in shock as he runs to look for Diane.
"TAI, COME HERE PLEASE!" screams Diane.
"What took you so long..." said Diane.
As Tai picked up the pieces, it reveals that the cat never ate Treasuremon, but with a bird.
"That's not Treasuremon, that's a bird." said Tai.
"Oh, I thought Treasuremon was dead." said Diane in a confused look.
"I think Treasuremon is inside-" said Tai before he finishes his sentence.
Before Tai could finish his sentence to Diane, the two heard Yugo humming the Wakfu theme song as he returns home from going out so he could help his adoptive father Alibert.
"Yugo came back, if he sees that Treasuremon is gone-" said Tai worried.
"Calm down Tai, maybe Treasuremon is still okay." said Diane as she calms Tai down.
As Tai and Diane remained silent about Treasuremon for five minutes, Tai will go inside to tell the truth about Treasuremon.
"No, Treasuremon is okay, I've remember that Yugo transforms him into Raccoonmon when he rescued me, I'll tell Yugo the truth." said Tai.
"Who's Raccoonmon?" said Diane who is confused who is Raccoonmon.
As Yugo entered his adoptive father's house, he gasps as he looks Treasuremon eating a cracker when Tai and Diane entered inside. Alibert has also looked at Treasuremon off-screen, he is so shocked too.
"*gasps* What happened in here!" gasps Yugo.
As Yugo returned inside, it is revealed that Treasuremon is eating a cracker and made a mess, causing him to scold Tai and Diane when Diane laughs at Treasuremon.
"That's not funny you two." said Yugo as he scolds Tai and Diane.
"Yugo, don't scold them." said Alibert.
"He's right Yugo." said Agumon.
"Treasuremon, what happened to you." said Yugo.
"Eating a cracker." said Treasuremon as he eats a cracker.
"It's not your fault right." said Yugo.
"Nope." said Treasuremon as he eats a cracker.
"I think I forgot to close the window in my room." said Yugo as he forgets to close the window in his room.
"Yugo, I've told you several times not to left open the window." said Diane.
"Sorry Diane.." said Yugo.
"I like crackers." said Treasuremon as he loves crackers.
As Treasuremon eats and loves crackers, Yugo, Diane, Tai, Agumon, and Alibert laughs and Yugo will close the window in his room after he accidentally left open it.
