You had been living with Cedar for...about a YEAR now? And they like you and your home.
And you like feeding them...a little too much.
You kinda constantly spoil Cedar with sugary treats and desserts as much as you could, & the more you did the more weight they gained, it wasn't like they could experience illnesses from the amount of sugar they get, but that didn't mean they couldn't experience immobility.
Fast forward to the present day, you arrive back home to feed your "little" buddy again, bringing in a massive cake.
You chime to Cedar that you were home, making the once dozing fairy, sitting in the empty flower pot in your living room, suddenly perking up at the sound of the door.
"Wh...m-my feeder! Hello!"
"What's in the bag!! Heh, heh, tell me!" They panted as they try reaching for the bag, they were plucked out the pot & placed in the kitchen on the floor, allowed to transform into their taller form, looking like the fat, immobile blob they were, resting on their own layers of fat.
"Huff...huff...cake...caaaaake..." The fae whines, reaching with the inability to reach.
