"decem crustulaS velim" is accepted but wrong (I think)
I don't know how to report that.
Duolingo has added an option "My answer should not be accepted" to most of the lists for reporting errors.
Just click on the "Report" link on the question page.
Should it not be crustulas because acc. pl. -um becomes -as? Or is velim an "objectless" verb like esse where both sides of the verb are nominative?
crustulum is neuter so the accusative and nominative are the same. crustula is both the nominative and accusative plural (as well as the vocative).
