Tubular Bells manifests mainly upon Mike O.'s application of his ability. His balloon animals in particular assume some independence, and take on small, shining eyes. The various shapes Mike O. makes his balloons into were inspired by different types of balloon art.
Tubular Bells is mainly a versatile ability-granting Stand which enables Mike O. to create semi-automatic balloon animals, thus allowing him to deploy his Stand over long distances and have a comparatively wide array of options during a fight.
Tubular Bells grants its user Mike O. the ability to inflate metal items by blowing into them like balloons and likewise shape them into automatic drones he can command.
Mike O. simply has to blow into any metallic object, for instance nails, screws, fences or tin shutters, to inflate them like he would a rubber balloon. The inflated metal then seems to partially take on the characteristics of a balloon, as it is able to be easily reshaped by Mike O., floats midair and has great elasticity as it can fit inside narrow spaces.
Mike O. is able to modelW the metal, and chooses to create balloon animals most of the time, for instance, dogs out of nails or birds out of tin shutters. The balloons can be remotely modeled, and they act on Mike O.'s command, able to follow simple instructions. For instance, he can register someone's scent into a balloon, which will automatically attack anyone with the same scent. However that autonomy also means that the balloons can be lured into attacking someone unrelated.
When the balloon animals make contact with their target, they burrow into their body and revert to their original form, harmfully embedding their constituent object there. By converting a flat heavy metal object into a floating balloon, it is possible to fashion a guillotine with enough potential energy to tear down a wall.
