You have ROBUST twice; I had REBUKE to replace one of them.

Also, I think it's NEBULA, not NEBULI; and TIBULA isn't a word, but TUBULE works.

TABULA may be acceptable though my dictionary lists it only as part of the Latin phrase "tabula rasa". My dictionary also lists TABUED, but I think that's taboo.

The doctor is correct, and REBUKE needs to be in the first six (ends with a vowel).

However, fibula sure sounds like a bone name, and nebuli might pass for plural, heh.
