D&D 5E (2024) Real Historical Animal Armors - what benefits should they give?

[BookTenTiger]

I saw these great armors made of animals (or just designed like them) at the Fernbank Museum in Atlanta today. What mundane or magical benefits do you think they should grant?

Here are some ideas:

River Spirit Armor: this leather armor is possessed by the spirit of a massive crocodile that fiercely guarded its river territory. As a reaction to being targeted by a melee attack, the wearer can summon spectral crocodile jaws that bite and grapple the opponent.

Pufferfish Fez: as a bonus action, the wearer pulls on a fin and the magical hat activated. The wearer's clothes inflate with air and they are launched 30 feet straight into the air. They gain a fly speed of 10 feet.

Crab Claw Helmet: the claws of this magical helmet can hold two small weapons, such as daggers, which make wild attacks against a random adjacent target.
