Oliva's Forest Nemona guides Liko and Roy to the forest Brassius mentioned, with Mollie accompanying them after learning it has been recently devastated by a wildfire. While investigating, Liko encounters a Paldean Wooper that has been dehydrated by the fire. The local Pokémon take Wooper to a giant tree adorned with an ancient Poké Ball identical to Rayquaza's. The "tree" turns out to be the oversized Arboliva, who misunderstands their intentions and attacks Liko's party as Mollie tends to Wooper. Liko and Roy distract Arboliva long enough for Mollie to treat Wooper, calming Arboliva, who shows them the greater extent of the wildfire's damage to the forest.
