Bottlenecked

Bottlenecked is a Side Quest in Mario + Rabbids Sparks of Hope, located on the planet Terra Flora, specifically inside the Everbloom Tree.

When the heroes reach to the Ooze Inside the Everbloom battle, they can find a side path to the right, leading to a pushable block puzzle. At first glance, there is one block, one switch, and two destructible rocks. Beep-0's Wave Power must be used to destroy them, with one rock revealing a second block. The heroes must destroy a cracked wall using said power to reveal a second switch. Both blocks must be pushed onto the switches, causing two gates to open up, unlocking a path to a treasure chest. Upon opening the treasure chest, the quest is complete, and the heroes are awarded a Planet Coin.
