Take a look at the sentence again:
Chauncey would have __________ some of the squid eyeball stew if a long,
gray tentacle hadn't dangled over the side of the bowl.
The sentence requires the past participle of eat, an irregular verb. Eaten is the past participle.
| Verb | Simple Present | Simple Past | Past Participle |
| eat | eat(s) | ate | eaten |
Eatten, the form you chose, is a spelling error. Before you continue, review the rules for irregular verbs.
