The Riddle of Barrendale Mesa

""The Hard Hats work in sync, but need Mr. Safety Glasses' help to meet. He needs help as well however... ...so turns back to engage Mr. Hard Hat With a Mask in his endeavors. Yet if Mister-No-Safety-Gear-Whatsoever isn't set... ...their work is for naught and circuit is dead." I suspect the knobs here are the key to solving this riddle, but how?"

The Riddle of Barrendale Mesa is a Side Quest in Mario + Rabbids Sparks of Hope, located on the planet Barrendale Mesa, specifically at the Windmill area. It is one of the five riddles on the planets. The Quest giver is Professor Backpack.

After solving the second circuit puzzle, the heroes can take a shortcut to the crane, and this shortcut has the riddle and Professor Backpack, who is unable to solve the riddle. The heroes must connect a circuit puzzle on the wall.

There are four knobs to turn; each one rotates two pieces of the circuit. Some of these pieces are covered, and are unable to be seen. There are four signs above the circuits, each one has a Rabbid. The first sign has a Rabbid wearing a yellow construction hat, with its ears behind the hat, the second sign shows a Rabbid wearing a safety mask, the third sign shows a Rabbid wearing a yellow construction hat, with its ears in front of the hat, and the fourth sign shows a Rabbid without any equipment.

After the circuit is connected, the riddle will be solved. The heroes will obtain a Planet Coin, and a treasure chest will appear, containing a Star Potion. Professor Backpack then thanks the heroes for helping him solve this riddle.
