Sparking Confusion!

Some strange signals have started coming from Wela Volcano which are interfering with the process Lusamine uses to track the Ultra Wormholes so she sends the Ultra Guardians to Wela Volcano to investigate. However, instead of finding more Ultra Beasts, they instead find a group of Alolan Geodude & Graveler who appear to be taking food from the humans. Will they be able to solve the mystery?
