Swallowing Sound

Swallowing Sound is a Side Quest in Mario + Rabbids Sparks of Hope, located on the planet Terra Flora. It is a Darkmess Puddle that is found in a side path after the Foul Attraction battle. After the Darkmess Puddle is cleared, the quest is complete, and the heroes are awarded a Planet Coin.

Battle
The battle is always random, but the heroes must defeat all of the enemies across two small battlefields, which are connected by a pipe or separated. If it is the latter, then Jump Panels can be used to travel between them. There are several Depleters and Armored Goombas on the battlefield. After all of the enemies are defeated, the battle is won.
