By the pool, a person in a pink frog costume brandished a “Team Algae” sign and heckled two National Guard troops. “Let’s go algae, let’s go,” the frog chanted, along with something about “pond scum.”

The costume is the Portland Frog from the anti-ICE protests in Portland. The costume has been used at "no kings" type protests previously.
