[Game thread] Skull Ruins Pokerole

Spoiler

The Nuzzle attack does nothing at all, strangely. That makes D-Pikachu pretty nervous!

Xatu does a Future Sight, however:
Future Sight
(5)(6)(5)(1)(4)(3) (2)(5)(6)(6)(2)(6) It will be a critical hit!

A round passes, and a strange humming emanates from the pond. It splits into three part harmony. When the Future Sight strikes, it causes a giant cannonball, splashing a bunch of water and mud out of the pond!

Which reveals a score of Tympole, a few fat Palpitoad, and two giant Seismitoad sitting in the mud. The Palpitoad provide percussion with a smacking sound from their sound organs. The Tympole sing the high harmony, and the two Seismitoad provide a bass so deep and loud it is shaking the meadow. The effect I'm picturing sounds a little like this song, except wordless of course.

They don't seem aggressive, though the ones that took the Future Sight attack have wriggled away into the mud and ceased singing. The rest just seem to be enjoying themselves. The effect feels like they are singing to celebrate something or someone, though.

Heart bow in respect towards the Water/Ground Pokemon, in apology for the future sight. "I sorry for that great family of Pokemons. I get myself scare after see the odd movement of the Water, and I already get nuked by a few Electrode Explosion. I beg for forgiviness for Future Sight you guys." Then Heart have a idea. He grab the Pokeballs of Caesar, Rose and Netune and ask to the family of Water/Ground ground band. "Mind if I and my other Pokemon join with you guys to sing and celebrate too? This is a apologize for my previous behavior. I have some music instruments who could help." Heart put out the Shamisen, Brass Drum and the Acoustic Guitar.

If they permit @Iron, Heart, Xatu, D-Pikachu, Rose, Netune and Caesar will join with the music song! In this case Iron what instruments is better for this situation?
