Theme song

Mister Trouble never hangs around
When he hears this mighty sound
"Here I come to save the day!"
That means that Mighty Mouse is on the way
Yes sir, when there is a wrong to right
Mighty Mouse will join the fight
On the sea or on the land
He has the situation well in hand

So though we are in danger, we do not despair
For wherever there is danger he'll be there
He'll be there, on the land, on the sea, in the air!
We're not worrying at all
We're just listening for his call
"Here I come to save the day!"
That means that Mighty Mouse is on the way!

Theme song (Mighty Mouse: The New Adventures)

• Mighty Mouse: Here he comes, that Mighty Mouse
  Coming to vanquish the foe with a mighty blow
  So don't be afraid anymore
  Choir: 'Cause things won't be like they've been before!
  Mighty Mouse: Here I come to save the day!
  Choir: Thank goodness Mighty Mouse is on his way
  So let the trumpet players play
  For Mighty Mouse is here today!
  Mighty Mouse: Here he comes, that Mighty Mouse
  Just like a bolt from the blue with a heart that's true
  Fighting evil, fighting crime
  Choir:And always there in the nick of time
  Mighty Mouse: Here he comes to save the day
  Choir: And he will prove that crime will never pay
  So let the trumpet players play
  For Mighty Mouse is here today!

  Pearl: Let's just catch Harry, okay?!
• A large gear! The Domesday Device must be close by!
• Harry: You may have freed your miserable ship, but I have you, Pearl! And you're going to tell me where the Interstellar Federation hides the Domesday Device! Once I have it, I will have the power to conquer the universe! The power to rule the galaxy! The power to make the planets grumble at the sound of my name!
  Pearl: You're mad for power! That's all you want!
  Harry: Actually, I wouldn't mind a little money, too. So tell me, where is the Domesday Device?

  Harry: Don't tempt me!

• Mighty Mouse: Ah, this is the life. I hope no ants come along and spoil it! (ants come to picnic and leave Pearl's ship) I knew the one thing they couldn't resist was a picnic. By the way, where is the ship?
  Pearl: I'm standing on it. Don't worry, Mighty Mouse. We always carry a spare!
