The Hidden Bridge
From the Super Mario Wiki
The Hidden Bridge is the secret tenth level of Ancient Gardens in Mario + Rabbids Kingdom Battle. It can only be accessed by completing Top Banana, then returning to the Bamboo Islands and using Beep-0's Push ability to push two blocks to their respective buttons and revealing a submerged portion of bridge.
The first part of the level is divided into three levels: the lower level consists of two Ziggies behind partial cover and a Smasher out in the open, the middle level consists of a single Ziggy in the open, and the upper level consists of two Hoppers behind full metal cover.
The next part of the level features a rematch against Pirabbid Plant, who is behind metal cover and at higher ground. This map also features a few Ziggies, a handful of Smashers, and a single Hopper, most behind partial cover.
