Stumped at the Fountain Pokemon Legends Z-A Side Mission Full Walkthrough and Guide

Unlocked after Main Mission 07

An artist is stuck because of brambles. Can you help her?

[1] Talk to the artist. Large woody vines are blocking her view of the fountain, an unfortunate predicament.

[2] Use a Fire-type move to remove the bramble/vines.
・An example is a Fletchling's Ember or a Litleo using a learned Fire Fang.

[3] Talk to the artist again...there are more brambles somehow?

[4] Destroy the brambles.

[5] Talk to the artist...brambles galore? What the heck!

[6] Burn all the brambles

[7] Report to the artist one last time.

Spoiler!
It was a Phantump making all the brambles appear! Good news for it that the artist decided to make them their muse.
