Tentacles Helmet

Appearance
The Tentacles Helmet is an American football helmet that changes color to match that of the wearer's ink. On the sides is a black and white squid logo and down the middle is a thick green stripe edged with white. The chinstrap is white, and the face mask is a darker version of the wearer's ink color. On the forehead is a white rectangle with some Inkling text in black.

Trivia

 * The Tentacles Helmet is the most expensive piece of gear with in Splatoon.
 * The Tentacles Helmet is the only piece of gear from Splatoon that's not part of a special promotion like the SQUID GIRL Gear, the Traditional Gear, the CoroCoro Gear, and all the gear produced by KOG, that has not returned in Splatoon 2, and is not rumored to be returning like the Octoling Armor and the Octoling Boots. The reason for this is unknown.
 * Oddly enough, the Tentacles Helmet appeared in the March 8, 2018 Nintendo Direct, suggesting it would've returned in Version 3.0.0 (Splatoon 2), but it didn't.
 * Two similar helmets, the Deca Tackle Visor Helmet and the Octo Tackle Helmet Deco, which also were featured in the Direct, were released in Version 3.0.0.
