Brandon "Brand" Walsh (Josh Brolin)’s Timeline and Summary
Since all the Goonies (with the exception of Chunk) are together through pretty much the entire film, check out Mikey's Timeline to get a sense of Brand's journey.
The only difference is that Brand is delayed toward the beginning of the film when Mikey and his pint-sized cohorts tie him to an armchair. He has to "borrow" a tricycle and ride that to the beach, before catching up with the rest of the gang and joining them for the remainder of their adventure.
