Don Doko Don/World 9

Round 81
This round contains two Pierons; at the start of it, both of them will throw out four balls (which will transform into eight more Pierons when they land). A Brown Book, a Water Jar and a Marmalade Jar will also appear at some point, which can be collected for a temporary freeze on every Pieron, a speed increase and a power increase respectively - and it is also worth noting that the nine remaining rounds of this world are not any easier for Bob and Jim.

Round 82
This round contains four Kings of Kards; a P-Ball and another Water Jar will also appear at some point, which can be collected for a temporary increase to maximum power, and another speed increase respectively. Three of the platforms on which the Kings of Kards are standing are also too high for Bob and Jim to jump up to - which means that you will have to tap one of the Kards they will have generated with your hammer to stun him, and pick him up, jump up to the small platform that is level with one of them, and throw him at him to kill him (and repeat the process twice more for the remaining ones).

Round 83
This round contains six Pierons; another P-Ball will also appear at some time which can be collected for another temporary power increase. Remember that even though the dwarves nor the Pierons cannot stand on the curved platforms, once either of the dwarves throws a stunned Pieron that they have picked up he will slide down (or up) them on his flight into either wall - and three rounds from now, you'll have to throw Kards so that they slide up them.

Round 84
This round contains two Rabits, and one King of Kards; a Marmalade Jar will also appear at some point here, which can be collected for another power increase. The sixth to twelfth platforms are also too high for Bob and Jim to jump up to - so they will have to go the long way round the first, third to fifth (in reverse order) and second platforms to reach the King of Kards (but if they should fall to the ground at any time they will have to do it all over again).

Round 85
This round contains one Golem, Kard, Chaos, Iety, Pegon, Crystalman, Worm, Hiruda, Rakot with an exploding cake, Eatong, Rapet and Cookman; no powerups will appear on it, the Worm also can't be killed, and if Bob and Jim jump up to one of the squares of the first platform, they will be stuck there.

Round 86
This round contains four Kings of Kards; a third P-Ball and second Water Jar will also appear at some time, which can be collected for a third temporary increase to maximum power, and another speed increase respectively. Again, even though the dwarves nor the enemies cannot stand upon the curved platforms, when either of the dwarves throws a stunned Kard that they've picked up, he will slide up (not down in this case) them on his flight into either wall - and you shall have to stun the Kards, pick them up, and throw them so that they slide up the curved platforms and kill the Kings of Kards on here.

Round 87
This round contains six Minimams; a Blue Hammer will also appear at some point, which can be collected for the ability to throw it at the Minimams. The white platform in the centre of the screen also moves down and up as the tops of the first and third platforms are too high for Bob and Jim to jump up to.

Round 88
This round contains four Minimams; a Brown Book will also appear at some point, which can be collected for a stun on every Minimam (and, if they have been split into two or four after a hit, they will fall to the ground). The seventh, eighth and ninth platforms are also too high for Bob and Jim to jump up to.

Round 89
This round contains four Kinokongs, two Golems and one King of Kards; no powerups shall appear on this round, and the two white platforms on the left and right sides of the screen also again move down and up (for the tops of those second and third platforms are too high for Bob and Jim to jump up to).

Round 90
This round initially does not appear to contain any enemies; however, the illusion will soon be shattered as the magician boss from the end of the fourth world comes up from the bottom of the screen (see Round 40 for full description). Once you defeat him, you receive 5000 points and go on to World 10.
