'Free' was an overstatement - he was still trapped inside the mushroom cap after all, drowning in a syrup-like acid.
Still, he looked on the bright side in such situations, to mentally keep himself going.
“Nice to move again.” he thought, gripping the wall of the mushroom and trying to tear away a chunk of its flesh, yet to no avail.
In all this he had not panicked, but soon his own suit of armour which had kept him safe all this time sent him a message which did:
[Internal air supply - depleting]
[Air left: 1.3 hours]
His thoughts began to spin rapidly in his mind.

“No way to tell how far away they are.”
“All I can do is conserve my air.” he shook his head, “I should have filled up my air reserves to the brim. Too late to think about that now.”
“Save my oxygen... or find a way out.”
Channeling some mana into his suit, he first tried to punch his way out.
