Seafoam Islands are a micro-archipelago in Kanto environed within Route 20.
It is a labyrinthine domain of islands that interconnectively encompasses two diagonally adjoined, nearly identical islands. Due to the exterior impassability of Route 20, voyagers must interiorly travel through both islands in order to reach the contradirectional segments of the route; therefore, this area must be passed through in order to access Cinnabar Island for the first time.
Notable miscellaneous
Articuno
An overworld-interactable Articuno inhabits the bottommost floor of the caves.
While this Articuno is not catchable, you will automatically register its seen-data entry in your Pokédex by battling it; this is needed for the Mew quest, which stipulates that 150 seen-data entries of Generation I Pokémon is needed in order to access Mew's inhabiting island, including Articuno's.
If you have battled this Articuno yet have lost its seen-data entry, you can use the restitutionary machine in Professor Oak's lab in Pallet Town in order to recover it.
Nurse Joy
A Nurse Joy is found stationed on B4F available to Kanto champions; usage of this service spares the strenuity of making Pokémon Center trips in order to heal, allowing trainers in the cave to proximately heal their battle-ravaged Pokémon.
She will heal the entirety of your lineup for 
1,500 per recuperation.
