Answer:
I am a ship that can be made to ride the greatest waves. I am not built by objects but built by minds.
I am clean when Iām black dirty when Iām white.
I am easy to see, but no one likes looking at me. Without me, there would be no you. What am I?
I'm blue, but when you see me I'm red. You don't see me too often. I'm there for you if you're hurt, but I'm good for you. What am I?
I run around the streets all day. Under the bed or by the door I sit at night never alone. my tongue hangs out waiting to be fed during the day.
I will disappear every time you say my name.
