Seabury

Seabury (pronounced "C berry") is a yellow Seadring with glasses that lives in Dreamy Driftwood Shore in the game Mario & Luigi: Dream Team. When the Bros. meet him, he starts telling jokes to them, but Mario and Dreamy Luigi don't find most of them humorous. The former then tells him about the Dream Egg. Seabury spits out the Dream Egg and disappears once he says one more joke.

Trivia

 * His swirly glasses might allude to Fawful from previous Mario & Luigi (series) games.
