Bob and Jim
These two bearded dwarves are the protagonists of the game; Player 1 controls Bob (shown to the left), while Player 2 controls Jim (shown to the right). They are on a mission to save the blue-haired princess of "Marry Land" (who has been kidnapped by a herd of flying pigs) and must make their way through its five worlds, each one comprised of ten rounds, by tapping the various enemies with their hammers to stun them, then picking them up and throwing them at the walls to kill them - and most enemies shall leave bonus items behind when killed which can be collected for extra points and special powers. Bob and Jim will lose one life whenever they are hit by an enemy (or anything that is fired at them by one); however, they will receive an extra life at 10000 and 100000 points (by default). There are also five secret keys that they can make appear on the first, twelfth, twenty-third, thirty-second and forty-third rounds, to be transported to five secret rooms - and, if they can manage to make all of them appear (and collect them), their game will continue for five more worlds (they can also make a sixth secret key appear in the first secret room to be transported to the "password room").

Enemies
All enemies are worth 10 points, when tapped with the hammer, and the ones that can be stunned and picked up are worth 100-200 points when thrown; each enemy hit by one is worth twice as much as the previous one. Iwangers also take six taps to kill - and they cannot be stunned, picked up or thrown.

Items
Most enemies will leave bonus items behind when killed, that can be collected for extra points; the Water Jars also give Bob and Jim a speed increase, while the P-Balls give them a temporary increase to maximum power, the Gray Hammer gives them an increase to maximum power (but, they shall not receive any points for the enemies they smash with it), the Marmalade Jar gives them a power increase (unless they are already at maximum), the Blue Hammer can be thrown at enemies, the Brown Book shall stun every enemy on screen, the Gray Book will freeze every enemy on screen and kill them, and the King shall freeze every enemy on screen (but without killing them). However, if you take too long to collect them, they will eventually disappear and may leave you in a tight spot - and it is also worth noting that even though the Green Spotted Apple is worth points, it will cause a power decrease.

Bosses
World 1 (Round 10) - The game's first boss is an enormous jack-o-lantern with a wizard's hat, a bow tie and five vines sprouting from him; there is a smaller jack-o-lantern (with a top hat) on the end of each vine and as he comes down into view from the top of the screen and begins rotating in a clockwise direction all five of the smaller lanterns will spit flames at Bob and Jim. The flames will also momentarily scorch the surface of any platform they land on (including the ground at the bottom) which can again kill Bob and Jim if they are standing on them - and you will have to stun the small lanterns with a tap from the hammer, pick them up, and throw them at the large lantern (his vines will instantly grow replacement lanterns whenever you do it) to damage him. Once you have thrown five small lanterns at him the speed of his rotation will increase; once you throw five more small lanterns at him he will explode and you will receive 5000 points and go on to World 2.

World 2 (Round 20) - The game's second boss is an enormous version of the Rakots with yellow dungarees; an infinite amount of Rapets will also emerge from those two doors, at the top-left and top-right corners of the screen as he comes down into view from the top of it and now starts flying around while throwing exploding candies down at Bob and Jim (which will, once again, kill them if they hit them). You will have to stun those Rapets with a tap from the hammer, pick them up, and throw them at him to damage him - and once you have thrown ten Rapets at him, he will explode, and you will receive 5000 more points, and go on to World 3. It is also worth noting that there are two different versions of this round; the harder one (shown in that screenshot to the left) features platforms which act like conveyor belts but the easier one (detailed in the Walkthrough) does not.
