Fly Agaric

Overheard today whilst stick collecting...

"What is it?" 

"a mushroom"
"a Mario mushroom!" 

"so it gives you boost powers!"
"let's show everyone"
"no we should just keep it. Half each."

Thought I should strategically wander past at this point. Some Google Lense action later and they found out it's not all that good for us to eat. (although is apparently hallucinogenic and has been used as a sacred drink in India and Iran)
