Donkey Kong Country/Winky's Walkway

The K is located a few steps to the right, reaches by a simple jump. The DK barrel is right after it. Eventually, the walkway stops in front of a Necky. Use it as a springboard to cross the gap. Continue advancing, and you should encounter two Neckys guarding a Winky prisoner crate, which can be reached by a jump attack on one of the two birds. With winky, proceed right, using a jump to collect the O. A few platforms later, you can break the checkpoint barrel.

After the checkpoint, you will find a barrel creating Gnawtys before another gap. If you didn't bring Winky with you, you can reach the other side by a rolling jump. After this jump, you will see a Necky on a simple patrol under a blast barrel. Jump on Necky to reach this barrel, to enter a small bonus room containing an N, which will drop you behind a Gnawty spawner (not too far, and you didn't miss anything important).

Continue to the right. You should come across an animal icon being circled by a Zinger, and you can't obtain it without Winky. Continue right, wait for the Necky to be high up, and stomp it to get the G. From here, you shouldn't be too far away from the exit, but will have to pass by another Gnawty spawner.
