The seasons are hopping!

Vivaldi's bark is all rhythm! The perfect all-season fighting companion.
This little Trunknid was nearly firewood. The terrifying prospect resulted in completely wacky foliage!
One day all's blooming, and the next all the branches are bare!
Take good care of your twiggy friend, all it needs is your love!

Despite the seasonal quirk, Vivaldi is an excellent ally in combat!
Choose from among various skills:
BUD: Adds Awakening to Oropo.
FLOWERING: Boosts a random Armor card in hand.
HIBERNATION: Has a chance to grant Tenacity to Oropo.

Take care of Vivaldi to make your relationship grow!
The more you play with this companion, the stronger its skills will get as you progress in the game.
But like any creature, this Trunknid needs a special diet.
If you want it to level up, you'll have to find as many Ecaflip chests as you can.
You may end up taking risks, but hey, you'd do anything for this little ball of bark!
