Answer:
What always ends everything?
I am cracked by Indiana Jones.
Take away my first letter take away my second letter take away all my letters and I would remain the same.
My first is in some but not in all. My second is in tiny but not in tall. My third in little but no in big. My fourth in port but not in pig. My whole is made in nature's way. For clothing rugs used every day.
What is easy to get into, but hard to get out of?
Though not a plant, has leaves. Though not a beast, has spine. Though many wouldn't need this thing, It's more valuable than wine.
