A Life Fountain? Appear good... But currently, us have Doc Moore, who can heal
you free. And if he is dead, it's the player fault.

Nevertheless, having a Life Fountain in some private house appear good. When you
click in there, tux could blink green, heal_tux() could be called and could be
wrote in the console: "Tux take a sip from the Life Fountain and he now feels
restored!", and after that, refresh tux heat.

Sounds cool!
