Here is how the Shadows attack and Mumfie saves Twilight and her friends in Mumfie's Equestrian Journey.
That night, Queen Novo honored their old and new friends with a banquet for their arrival.
Queen Novo: (tapping her glass with a spoon) Can I have everyone, everypony, and every creature's attention please?
Mumfie: Quiet, everyone, everypony, and every creature!
Queen Novo: (as everyone paid attention and she looked at Mumfie) Thank you, Mumfie. (clears her throat) Now that I have everyone, everypony, and every creature's attention, I would like to honor the arrival of Prince Derek, Princess Odette, and company, especially Mumfie and his Alliance of Friendship. So, let's enjoy the occasion for tonight.
Mumfie: Cheers!
As they all raised their glasses of their drinks, Mumfie was glad to share his honor.
Silverstream: Best Banquet Ever!
Princess Skystar: Woohoo!
Benjamin Hood: Yes!
But suddenly, one of the shadow demons snatched Twilight and her friends out of nowhere.
Twilight Sparkle: Help!
Luster Dawn: Princess Twilight!
Mumfie: Don't worry, I'll save you!
With a few tricks up his sleeves, Mumfie used the bright light spell to take out the shadow demons one by one.
Mumfie: That takes care of them.
Grubber: Fizz, did you see that?
Fizzlepop Berrytwist: I sure did, Grubber.
So, he ran up to Twilight to see if she's okay.
Mumfie: Are you alright, Twilight?
Twilight Sparkle: I'm okay, Mumfie.
Queen Novo: What just happened!?
Louis: Those shadows were attacking, they belong to the Shadow Man.
Puffin: You mean the one that Mickey Mouse and his friends faced?
Louis: Yes.
Twilight Sparkle: But at least we're all safe, thanks to Mumfie.
With Mumfie being thanked by Twilight and her friends, that got him thinking about being special.
