This is how Battling the Great Carapace goes in My Little Pony Transformers Prime: Battle for Volcano Island.

[We see Danny, Spongebob, Optimus, Twilight, Starlight, and Rocka are walking when they hear screaming and see crabs running across a bridge]

Crab #1: The Great Carapace...

Crab #2: ...has come to life...

Crab #3:'s destroying out town...

Crab #4: for it!

[A giant Terrorcon with a wooden shell appears]

Danny Phantom: What is that?!

Spongebob Squarepants: It's a huge Terrorcon, wearing a big wooden shell.

Optimus Prime: Created from Unicron's life-blood. Dark Energon.

Twilight Sparkle: We can use our friendship magic.

Starlight Glimmer: I'm with Twilight.

Rocka: Let's kick some Terrorcon butt.

[The Terrorcon sees the Wise Old Crab]

Spongebob Squarepants: Oh, no. The Wise Old Crab is in danger. To the rescue.

[The Terrorcon swallows the Wise Old Crab]

Spongebob Squarepants: Oh, no! It swallowed the Wise Old Crab!

Optimus Prime: Fear not, absorbant yellow one. I have a plan.

[The Terrorcon sets its sight on Danny, Spongebob, Optimus, Twilight, Rocka, and Starlight and starts to attack them]

Optimus Prime: Now!

Terrorcon: [roars]

[The Terrorcon tries to break free as the wooden shell starts to break]

Terrorcon: [roars] (translation: You can't defeat the Great Carapace!)

[The shell finally breaks and the Terrorcon turns to stone]

The Wise Old Crab: As was foretold in legend. You
