The Maginaryworld monsters are creatures that appear in the Sonic the Hedgehog series. They are inhabitants of Maginaryworld, with three unique monsters and one boss monster on each board (except for Fourth Dimension Space, which has only two common monsters). Special monsters guarding pieces of the Precioustone also appear on every board.
A battle with a monster initiates any time a player lands on a Battle Space or on a space with a piece of the Precioustone on it, and Doctor Eggman can place monsters on regular spaces using one of his inventions.
Battle[]
Battle Space
Each monster starts the battle with a Magical Card numbered from one to six above them. In order to fight the monster, the player selects one of their own Magical Cards of equal or higher value. The selected card spins from one to its number value, and the player must press 
to stop it on a number.
If the card's number is higher than the monster's number the player will land a successful hit, or if the player's number is equal to the monster's it is a "Critical Hit", both of which cause the player to win the battle. If the card's number is less than the monster's card, the attack will fail and the monster will counterattack with its own card roulette.
If the roulette results in a card of higher value than the player's, it will deal -10 rings of damage and end the battle. If the player loses a battle without any rings, they will miss a go.
Forcejewels can also be used to influence the result of the battle in various ways. A battle win can reward the player with Forcejewels, or a Precioustone piece when winning against a Precioustone monster.

A winged rocket or torpedo that attacks by firing its own rockets from underneath.  A winged mechanical fish resembling some of the flying fish seen in Emerald Coast. |
A mechanical phoenix much like the board itself serves as the boss of Fire Bird. The light blue piece of the Precioustone is visible in its cranium, and it has Void's pillar markings on many of his body and neck segments.
Nature Zone[]
The Nature Zone's monsters are wild animals and plants; however much like their habitat their designs are corrupted by Void's influence.

Riot Train[]

Fourth Dimension Space[]
The monsters of Fourth Dimension Space are abstract and geometrical in form, reflecting their dreamlike environment.
The Fourth Dimension Space boss closely resembles the Precioustone monsters, with the dark blue piece of the Precioustone at its core and a long insectoid body or head, with eight segmented limbs along its sides and Void pillar patterns spreading from spikes on its front.
