Don Doko Don/World 6

Round 51
To reach this round, you must uncover and collect the secret key in the first round, then enter the doors to the first secret room, then uncover and collect the second secret key to enter the doors to the Password Room and smash the jars in the correct order; it contains four Kinokongs, three Pink Kinokons and two Brown Kinokons. A Water Jar and Marmalade Jar shall also appear at some point here, which can be collected for a speed and power increase.

Round 52
This round contains nine Kinokongs; a Gray Hammer, another Water Jar and another Marmalade Jar will also appear at some point here, which can be collected for an increase to maximum power, another speed increase and another power increase respectively. The next round has unreachable items.

Round 53
This round contains five Kinokongs, two Pink Kinokons and one Brown Kinokon; a P-Ball and Water Jar will also appear at some point, but they cannot be collected because the fourth platform is too high for Bob and Jim to jump up to. The enemies can also once again go into the mouths of the trees on the left and right sides of the screen to go up (or down) a level, but Bob and Jim still cannot - which is why they can never collect the items that appear.

Round 54
This round contains four Kinokongs and four Rabits; a fourth Water Jar will also appear at some point which can be collected for a third speed increase. Also, once Bob and Jim jump up to the top half of the platform, they will be stuck there - and the enemies can, yet again, go into the mouths of the trees on the left and right sides of the screen to go up (or down) a level, but Bob and Jim still cannot, but this is the last time they will have to endure that fact.

Round 55
This round has five Rabits, two Orange Pigumns, three Yellow Pigumns, and three Magenta Pigumns; a fifth Water Jar shall also appear at some point which may get collected for a fourth speed increase. The platforms on which the Pigumns are standing are also too high for Bob and Jim to jump up to.

Round 56
This round contains five Pink Kinokons and four Brown Kinokons; a Brown Hammer will also appear at some point, and the two plants on the underside of the third platform will also drop more berries (lethal if touched from the sides) which Bob and Jim will have to jump on and ride to reach the platforms.

Round 57
The round has four Kinokongs, two Rabits, one Orange Pigumn, two Yellow Pigumns and one Magenta Pigumn; a sixth Water Jar and third Marmalade Jar shall also appear here, which can be collected for a fifth speed increase and third power increase respectively. The four plants on the undersides of the first, fourth and sixth platforms will also drop more berries on Bob and Jim but they are not required to jump on and ride them to reach the platforms.

Round 58
This round contains one Kinokong and six Iwangers; another Gray Hammer will also appear at some point, which can be collected for another increase to maximum power. Also, you should remember that the Iwangers cannot be stunned, picked up or thrown, and take six taps with your hammers to kill.

Round 59
This round contains two Kinokongs and three Iwangers; another P-Ball will also appear at some point, which can be collected for a temporary increase to maximum power, if either player has died, or collected a Green Spotted Apple. The two carved faces on the left and right walls will also occasionally wake up and yawn before going back to sleep again causing four rocks to drop down from the top of the screen and roll towards the bottom on the left and right sides (which are, again, lethal if touched in any way) - and the next round also features the enormous jack-o-lantern boss from the first world.

Round 60
This round initially does not appear to contain any enemies; however, the illusion shall soon be shattered when the enormous jack-o-lantern boss from the first world comes down into view from the top of the screen (see Round 10 for a full description). Once you defeat him, you will proceed to World 7.
