Press the switches to adjust the direction of the barrel and launch from landing to landing. You’ll first encounter a horde of Gnawty mice and see some armadillos. The “K” letter is by the edge with one barrel. Press the switch to make one barrel face down and launch down where a lone banana is. The first bonus area has the “O” letter over a collapsing cloud but avoid the Zinger. Back in the main area, launch again and you’ll reach the checkpoint. Rather than blasting through to follow the bananas, blast towards a secret barrel. The 2nd bonus area has Mincers guarding 2 tokens and the “N” letter. Back in the main area, keep launching and you’ll find the “G” letter. Launch from one more barrel and you’ll find the goal.
