It felt cold at first, forcing his metabolism to increase the heat distribution. But other than that, Indiana felt comfortable that he went deeper, descending into the depths of water while holding the air in his lungs. Once he was sure of his footing, Indiana began to punch and kick underwater as though performing some resistance exercises with his limbs to work the muscles in them.
It was only after three minutes that Indiana felt his lungs burn and he quickly resurfaced for air.
"I'm getting a bit rusty in holding my breath." the youth muttered to himself. After inhaling, Indiana quickly descended back down into the lake to resume his activities. The only comfort he had was that his movements underwater haven't missed a beat even though it had been some time since he did underwater exercises.
After resurfacing to recover and for air once more, Indiana descended back down into the lake but this time, he planned on exploring. The youth had found an interesting ground filled with some platinum-white sand and some rough-looking rocks.
But Indiana felt something wasn't right and instincts were telling him to head to the surface. As he turned to swim to the surface, the ground exploded in clouds before the youth felt something wrap around his leg along with the sensation of suction caps. Indiana had liberated his leg from whatever had grabbed him before swimming as fast as he could for the surface. Whatever had grabbed him didn't make another attempt such that as he reached illuminated waters, Indiana turned and saw an ominous red-eyed giant octopus.
The creature didn't move to capture him before retreating into the darkness of the waters and Indiana decided not to give it another opportunity to do so as he swam and reached the surface.
