DecapAttack: Round 6: Last Leg Land
Last Leg Land is amply-named, because it's the other leg-shaped island you have to rescue.
Which means except to see Chuck slipping and sliding a lot more than usual in this Round! However, SOMEHOW... this icy Round still manages to have those nosy lava pits!

6-3's missing item happens to be... a magnifying glass? Hmmm... whatever works at this point.
The boss of Round 6 is a giant Yeti, though the boxart of this game made him come off more as a huge ape. It seems like you can only hurt him when his hands aren't on or near his chest, such as when he grabs the top of the screen (he's literally clung there, even when you jump to move the camera up) to spit snowballs at you, or... when he just stands around to do a little jig.
This is the last boss before the final confrontation against Max D. Cap, and this also makes it the last time you can go through the Bonus Stage.
