Baby Mario and Baby Peach: Dynamic Duo

Baby Mario and Baby Peach: Dynamic Duo is World 1-7 of Yoshi's Island DS. In this level, Baby Mario and Baby Peach (and the Yoshis) must use teamwork to get to the goal. This level's playable Yoshi is the red Yoshi.

Layout
The first section of the level contains many M Blocks, as well as several Crazee Dayzees. A group of M Blocks separates a wind current and a flower from a tall cliff. Baby Mario must climb up M Blocks to a Stork Stop, so the M Blocks disappear and Baby Peach can ride the current to the top of the cliff. The rest of the section works the same way, using both babies to dash and to float on wind and climb M blocks to the end of the section. There is also a Super Star practice room down a pipe in the level.

The second section introduces the player to transparent M Blocks, which Baby Mario can hit to make them appear. Baby Mario must hit several transparent M Blocks, and climb up to a Stork Stop to change to Baby Peach so the player can continue the level. Then, Baby Mario must hit more transparent M Blocks to make a staircase to some wind for Baby Peach, leading to the third section of the level. In this section, there are some walls that Yoshi can go through. After walking through the passage (filled with Tap-Taps) and having Baby Mario climb up a staircase of M Blocks, Red Yoshi transforms into a Mole Tank. The Mole Tank must smash through a lot of soft rock, and then Yoshi drops down a pipe to the fourth and final section. Then, the Yoshi must get through some more underground areas by using teamwork with the babies. At the end, a wind current and the goal roulette can be found.
