and since you love riddles, JGJ, heres another one for you:
We are little creatures;
all of us have different features.
One of us in glass is set;
one of us you'll find in jet.
Another you may see in tin,
and the fourth is boxed within .
If the fifth you should pursue,
it can never fly from you.
What are we?
