You could say I like traveling and I'm usually with my friends, unless I'm not needed, I can stay hidden for years.
Quite the collection! You'll find items of many calibers; just don't get lost now!
Sensitive to heat, I have a solid form, protected by my master's gown; I'm something you'll never turn down.
Holding onto me is ill-advised, though, as with many times before, it is hard to say goodbye.
I am myself, but you may not know, for when I use this, I can be anyone - even a puppet show.
I cover the earth far and wide, for the sun is my best friend; this you cannot deny.
I start off empty and click like a switch, for all I need is just a little twitch.
