Lava Lagoon
Head down just to the right of the fourth Clapper (seal) after
the continue barrel (the first Clapper after [G]). There is an
invincibility barrel and a hidden corridor; follow the trail of
bananas to the DK coin and then onward to the end target.
Use the barrel after the first "no Enguarde" sign to
break open the left-hand side of a nearby crate (a lone banana
marks the crate to open)
