Scratch

I'm making a game, and in a point in the game, I want the player to be able to chose a name for his character. For this, I used the "Ask [_____] and wait" block, so that the player can type his name below. Also, at that point, the background is black, and the sprite is just some letters in white saying: "Choose your character's name". The only problem is that when I put the "ask and wait" block, a speech bubble pops up from the sprite, and it doesn't look good at all.
So my question is, is there a way to ask a question without the speech bubble popping up?
