No, puffer fish spikes are not hollow. Instead, they are made of a hard, keratin-like material and serve as a defense mechanism against predators. When threatened, puffer fish can inflate their bodies and erect these spikes, making them appear larger and more intimidating. This physical adaptation helps deter potential threats.
There is a puffer fish pin. Also, in the game aqua grabber, they can poke your sub with their spikes.
