Well, it wasn't exactly the rest of the gang, but Sora & Mimi, as well as their Digimon, Biyomon and Palmon. The digimon were in disguise as well.
" Angewomon, what are you doing here?" Biyomon said, as she instantly saw through her disguise.
So Angewomon told them of Kari's plan to get fat. It sounded a little crazy, Angewomon added, but it was what Kari chose to do. After the story, Sora was in deep thought.
" You know, I was thinking how cool it would be if I was fat too. To stuff ourselves until we couldn't move. Don't you think so, Biyomon?"
" Now that you mention it Sora," Biyomon replied, " I always wanted to try some of your food."
So, before the day was all over, Sora and Mimi, as ell as their digimon, decided to join Kari inher gaining adventure.
" We'll go get some more food for us 4."
And with that, Sora and Mimi went to basically every place Angewomon went to, buying several more burgers, pizza, hotdogs, fried chicken, and Milkshakes, Ice Cream, etc... They basically went grocery shopping in the food court, and mimi paid for it with her credit card.
With all of their handsfull with food, the Group of 5 made it back to the Kamiya;s Apartment.
