Baby Mario and Baby Peach: Dynamic Duo

Babies Mario and Baby Peach: Dynamic Duo is Level 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.

The first section of the level contains many M Blocks, as well as several Crazee Dayzees. A horde 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 that section works the same way, using both babies to dash, float on wind and climb M blocks to the end of the section. There is also a Super Star practice room down a pipe, although the next appearance of a Super Star is in Level 4-8.

The second section introduces 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 in 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. Directional arrows peculiarly point into a wall, although it turns out that you can walk into secret passages inside the walls. 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 Red Yoshi 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. The game introduces Arrow Clouds and Tulips, and then there is a wind current and a couple more bypasses through walls to the Spinning Goal Ring.
