The Adventures of King Ragomite and His Ragoknights - K. D. Holmes - Bog

The story begins in King Ragomite's castle, where everyone, except the king, is preparing for a ball, which is a cover for his birthday. The story shifts to the Thunder Ridge Forest, where the villain, Jeremiah Foxtrot, commands his Muskrats to commit evil deeds. The Muskrats are caught in a storm and shelter in a cave where they find the hidden portal between realms.
The Muskrats tell Jeremiah of their findings and later are sent to survey the other realm and bring back the most valuable thing there. They decide to lure their target, the king, to Thunder Ridge Forest by kidnapping Princess Dominia using baker disguises and a large hollowed-out pumpkin. The king is distraught when he finds out, and then shares the news an ancient foe has come back to haunt them.
