There are seven different Elements (some players refer to them as Types) that can be applied to the various Monsters all throughout the world of Vulpin Adventure. Types are often applied to the various Moves as well, mostly to determine what Monsters they are effective or ineffective against.
Earth
The Earth typing is the one applied to the majority of the life that lives in the Woods. This includes the Mot, the Mushmuncher, and the Hedgewolf, as well as that area's Boss Monster, Calyx. The Earth type is strong against Water-type monsters, but weak against Air-type monsters.
Water
The Water typing is the one applied to the majority of the creatures in the Sea Cave area. This includes the Seahorse, the LobsterMonster, and the Snoroceros, as well as that area's Boss Monster, Hydrex. The Water type is strong against Fire-type monsters, but is weak against Earth-type monsters.
Fire
The Fire typing is the one applied to the majority of the life in the Desert Ruins. This includes the Renegade Reptile, the Inpu, and the Flaming Fossil, as well as the area's boss monster, Drakhbet. The Fire type is strong against Earth-type monsters, but is weak against Water-type monsters.
Air
The Air type is the one applied to the majority of the life in the Cloudy Peaks. This includes creatures like the Scythe Wasp, the Chigrumpen, and the Dragon, as well as that area's guardian, Pterophor. The Air type is strong against Earth-type monsters, but is weak to the Fire type.
Dark
The Dark type is only applied to two species, the Darkdragon and the Final Boss. They can be found in Darklight Castle. This is the most uncommon type in Vulpin Adventure. The Dark type is strong against the Light type yet weak to it.
Light
The Light type is the type applied to the majority of the life in Darklight Castle. This includes creatures like the Fluffpuff, the Starwisp, the Lightdragon, and the Final Boss. The Light Type is strong against the Dark Type yet is weak to it.
Normal
This type includes the Vulpin, and the four Brushbeasts, as well as the Ducky and Monsieur Ducky creatures in the ??? area. This type is neither weak nor strong to any other type.
