Manny Gabblegoose

Manny Gabblegoose was originally established as the first mate aboard the Abraham in the second episode of Folk & Dagger. However Brendan forgot his name and renamed him to Fred Gabblegoose in episode 3. Then seemingly forgot Fred's name and just referred to to him as First Mate Gabblegoose in episode 4. However because the Gabblegooses are a large family, a Manny Gabblegoose is probably out there somewhere.
