Monster Island Adventures is a SpongeBob SquarePants online game.

It is a role-playing strategy game and a sequel to the Monster Island and Return to Monster Island online games, taking place in an island SpongeBob and his friends have to go through to deliver Krabby Patties a mysterious customer has ordered.



The game's gameplay shares similarities to other role-playing games, notably including the Pokémon ones, as the player has to choose between the four characters to attack a monster each time.

Each character has three abilities: a common character move, an ability that either heals or protects them and others, and a special one. The latter two can be unlocked, speed up, and upgraded through winning a battle, which gives the player a level point. They can be also spent for up to three costumes of the playable characters, with each one also having their individual abilities.

  • SpongeBob: Blow Bubbles, Cook Patties (restores health), Annoying Laugh
    • DoodleBob: Paint
    • Primitive Sponge: Ooga Booga
  • Patrick: Stand Very Still, Hide Under Rock (prevents all damage from the next enemy attack),
  • Sandy: Howdy, Science (adds a random weakness to the monster)
  • Squidward: Nag, Dance (character abilities become ready faster)

There are three attack types in this game: Sound (ear), Sight (eye), and Smell (nose). They can be seen alongside the outfits in the outfit selection screen, and alongside monsters the player has to deal with during gameplay, representing their weakness.
