Ceviché always seems to speak with a monotone inflection, regardless of what emotion he is actively expressing—whether it be fear, revenge, lovesickness, pain, happiness, or shock.
His opinion of musicals is higher than that of plays, as supposedly no one dies in musicals, indicating Ceviché is sensitive and prefers joyful entertainment. In "The Dice Cycle", he is also shown to be very kind and helpful, giving food to the poor, assisting old ladies in crossing the street, and much more.
He was made to be a love interest for Panini so there would be friction between him and Chowder.
- He is named after a Latin American dish consisting mainly of raw fish cured in citrus juices.
- In "Panini for President", it is revealed that Ceviché had developed a crush on Panini. This is later confirmed in "The Dinner Theater".

- Ceviché cries in almost every episode he's in.

- He is the only apprentice that was not shown in the episode "Chowder Grows Up".
