Fix It:
1. Capital: Capitalize "Grandmother" to "grandmother" since it is not a proper noun.
2. Commas: Add commas after "large" and before "amber" to separate the adjective clause.
3. Apostrophe: Add an apostrophe after "mermaid" to show possession.
4. Usage: Remove the unnecessary word "into" before "the palace" to improve sentence clarity.
