Elm Pokémon Lab - Pokémon HeartGold & SoulSilver

"Elm Pokémon Lab - Pokémon HeartGold & SoulSilver" is a high quality rip of "Elm Pokémon Lab" from Pokémon HeartGold & SoulSilver.

Joke
Starting at 0:04, the advertised track is mashed up with "Sunshine, Rainbow, White Pony", with plenty of pitch-shifting to match the track's chords. Parts of the melody are changed to "Sunshine, Rainbow, White Pony".
