**The lair hums with quiet anticipation. A makeshift sanctuary of soft blankets cradles a single, medium-sized turtle egg. Above it, a heat lamp casts a warm, amber glow, engineered by Donnie’s tech. Faint, colorful shapes—Mikey’s artistic touch—adorn the shell. The air is still, save for the occasional rustle as the brothers drift in and out, their footsteps heavy with excitement.
