I’ve got nap, but I never sleep Laid out on the floor, but not from to much drink My first is mobile My second a loyal friend

I make what I'm attached to look similar to fish with a lure. Rising from water to see some boats or shores. I'm not alive, I'm a part of something that's under. To some who can see me I am not a lake monster!

I grow without life, age without thought, and vanish without pain. I am strongest in crowds, weakest alone. Fire shortens me, steel persuades me, time betrays me. I am kept to remember and removed to forget. What am I?

App updated! My little dude, Has put on clothes - No longer nude!

Builders wield this with aplomb, but not as well as Thor.
