Pay all 47 Kremkoins at Klubba’s Kiosk to open the whole Lost World in Donkey Kong Land 2. The Game Boy order is Jungle Jinx, Black Ice Battle, Fiery Furnace, Klobber Karnage and Animal Antics. Complete those stages to open Krocodile Kore.
Each of the five bonus challenges awards a DK Coin. Find the entrance, finish the objective and take the coin before time expires.
Jungle Jinx
Cross the jungle gaps using the hooks and Flitters, leaving room to land beyond the Zingers. This Game Boy stage does not use the SNES giant-tire route. After K, pass the two Neeks and Spiny to the bonus barrel floating beside the ground. In the ten-second challenge, cross the gaps and spikes, avoid the flying enemies and collect the DK Coin at the end.
Black Ice Battle
Descend the icy floors with controlled jumps, checking the lower landing before dropping past a Zinger. Beyond K, reach the Spiny and nearby Zinger, then jump up-left from the slope on the Spiny’s right. Invisible hooks lead upward to the bonus. You have fifteen seconds to descend its icy route, avoid the Zingers and reach the DK Coin.
Fiery Furnace
Use the cannons and sinking hot-air balloons to cross the lava, transferring before a balloon drops too far. After the Continue Point, Squitter’s web platforms carry you over the gaps. Beyond the No Animal Sign, continue through the cannon section. From the landing, roll-jump left past the Zinger into the bonus barrel. Alternatively, fire right from the first moving cannon when it reaches its far-right position. The twenty-second bonus crosses lava using Krockhead switches and Flitters; collect the DK Coin at the far end.
Klobber Karnage
Keep clear of the Klobbers near narrow ledges and use barrels to remove a Spiny blocking a necessary landing. Near the end, enter the vertically moving cannon and aim downward into the visible bonus barrel. Collect all ten stars with the cannons over the gap within twenty seconds, then take the DK Coin that appears.
Animal Antics
The Game Boy route uses Rambi, Squitter and Rattly. Bounce Rambi over the Zinger gaps, build Squitter’s webs for the middle section and use Rattly’s high jumps for the final spikes. There is no SNES-style Squawks wind section here.
For the bonus, search the large gap immediately before the Star Barrel while still Squitter. Build downward toward its bottom-right alcove to find the barrel. Inside, create platforms to reach all 23 stars within forty seconds. Collect the DK Coin before returning to the main level.
Final battle: Krocodile Kore
Survive the long volley of ordinary and spiked cannonballs, watching their height before choosing whether to jump. The following barrel contains a usable cannonball. Release it and throw it into K. Rool’s blunderbuss when he inhales. This rematch needs one successful return after the barrage. Collect its DK Coin for the last of the forty and watch the final ending.
For a missing completion mark, revisit the appropriate world chapter and check both the bonus reward and DK Coin. A story clear alone does not finish the collection.
