More vines, with a few twists.

If Junior is careful and lucky, and he times it right, he can jump on the spring-loaded I-beam (look familiar?!) and leap up onto the small grassy island zipping back and forth. If he's extremely lucky, he might even jump all the way up and grab a dangling vine. The short one gets longer, shorter, longer, shorter...	Junior is more likely to jump across from grass to grass (some move) and climb the vines. At this There are birds on this board, too: Mario releases them and they fly to the right, then dive down and hook left. They drop eggs like bombs on Junior's position.
Junior has made it from vine to vine. The small grass piece, as you recall, moves back and forth—but so do the two hanging vines.	It's tricky across here, reminiscent of the Keys Level: birds are flying to the left, at different altitudes. Luckily, there aren't any steel traps. Here, Junior has made it to the right side where he is temporarily safe from everyone.
Success at last! Junior has achieved the key. But, like most of the other boards, he's robbed of his success when Mario pushes Papa's cage off the screen.
