memory P is a bonus song that appears in Pokémon FireRed & Pokémon LeafGreen: Super Music Collection, the soundtrack of FireRed and LeafGreen. It is performed in Japanese by Yumi Funasaka, and it is sung to the tune of the Four and Five Island theme, itself a remix of the Azalea Town/Blackthorn City theme.

| Every time I close my eyes|
My memories, like gems,
Pass through this "green" forest
And rise to the blue sky
What's waiting for me is probably
That nostalgic scenery
The flowers are blooming crimson
The "red" swaying in the rustling wind
Is approaching step by step
Which island should I go to next?
Bury the brand-new map
I'm sure I'll finally arrive
At the future I kept searching for
"Silver" waves approach the ship
"Gold" sunlight caresses my cheeks
My journey continues onwards
The endless adventure
Spins boundless dreams
Look, the world is connecting together
