Pax East is a video game themed convention that takes place every year. In 2018 ThinkGeek partnered with Cuphead to do a special promotion for this convention. Featured on the staff shirts is a battle between a Cuphead version of Timmy. I illustrated the ThinkGeek mascot, Timmy, and a sewer sludge monster in battle.

Each day a customer visits the booth they are given one of the buttons designated for that day. The con lasted 5 days and on the last day if the customer had collected all the buttons they are given a special larger button as a reward.
