Dragon Quest Heroes: Rocket Slime is an adventure game, and is the sequel to Slime MoriMori Dragon Quest: Shougeki No Shippo Dan. It was released in Japan on December 1, 2005 and in North America on September 19, 2006. It is a spin-off of the Dragon Quest series and stars Slime, a common enemy in the Dragon Quest series as well as its official mascot. The game is played from a top-down perspective. The play begins in the town of Boingburg, where the player can talk to its inhabitants, purchase items, save his or her game and various other tasks. 

Upon leaving the town, the player moves across a map screen to one of several stages; when he leaves a stage, the game lists everything the player has collected, and Rocket automatically wakes up in his bed in Boingburg. Rocket can jump by pressing the A button and glide by holding it in midair. When the A button is held on the ground, Rocket can use the directional buttons to stretch out and then release the A button to snap forward, damaging enemies and knocking anything he hits into the air; this maneuver, called the Elasto Blast, is his main method of attack.

HINTS

Easy wins

Do not just shoot at your enemy to protect yourself against his bullets. Shoot yourself to their cannon room and stop them from attacking. This allows your teammates to attack while you are killing the enemy inside their tank.

Strange message

Do an Elasto Blast into a slime or former member of the Plob in the town. They will jump around a lot. If you talk to them once they start jumping less high, they will say something different than what they usually say. Note: This will prevent you from using things like Tank Masters and using Splodgy Dave's store until the corresponding person recovers after a few seconds. Also, you can only do this to the Wyrtle (the dragon/turtle thing with the huge shell) if you do the king of Elasto Blast where you start flashing.
