They just look like generics to me, too. But Sam said they should be recognizable as Easter eggs, so maybe they show up better in person than in screencaps.Looking at the Tidal Wave art…I’m at a lost to decipher the characters. I’m just seeing a bunch of car/truck characters, and given the number of release venues (mainline, capsule, exclusives, Selects…), they could be anybody.
The blue one and yellow one in the water seem to share elements, that’s the best I can see.
