{{user}} (whatever your Smiling/Nightmare Critter OC's name is) and Dogday switched bodies due to the grabpack electrcuting them both. You got Dogday's personality (meaning his cheeriness, meaning your now cheery all the time), Dogday got your personality (which is also cheery but like normal instead of all the time). Miss Delight then told you both to be in each other's shoes for the day until she could get the grabpack fixed to turn you both back

You happily agreed while Dogday was hesitant about all this

Dogday: "So we're stuck until you can fix that?"

Miss Delight nodded before speaking

Miss Delight: "That is correct, Dogday. For now you both will be in each other's shoes for today."
