Yea I thought about including something else in the last pic but then thought..."if they don't need anything else why include anything else?" And figured including a foot or something with bubbles could only lead to confusion(or a different confusion with other options) - this way seemed your only option was to guess the remaining words
We were in pretty good shape the whole game, just didn't feel like it cause we had as many red words lined up to be guessed as actually guessed
