How would I correct this sentence if it is a fused sentence:

The creature sat upright and tugged at the shackles binding his ankles, Frakenstein uttered a piercing scream

The creature sat upright and tugged at the shackles binding his ankles, and uttered a piercing scream

is that what you wanted?

The creature sat upright and tugged at the shackles binding his ankles. Frankenstein uttered a piercing scream.

The fused sentence is after "ankles" in the original.

To correct a fused sentence, you need to separate the two independent clauses into separate sentences or use coordinating conjunctions to connect them. In this case, the fused sentence is: "The creature sat upright and tugged at the shackles binding his ankles, Frakenstein uttered a piercing scream."

To fix it, you can either split it into two separate sentences: "The creature sat upright and tugged at the shackles binding his ankles. Frankenstein uttered a piercing scream." Alternatively, you can use a coordinating conjunction like "and" to connect the two independent clauses: "The creature sat upright and tugged at the shackles binding his ankles, and Frankenstein uttered a piercing scream."

Both of these revisions separate the actions of the creature and Frankenstein into distinct sentences or join them with a coordinating conjunction, correcting the fused sentence structure. Great job on your revision!
