I actually bought their Immune System book, just cause I’ve enjoyed their stuff for so long. I remember those stupid little birds over a decade ago, and the book serves a little more purpose than their general merch. It’s also really well illustrated. Haven’t had the time to read it yet, as it’s pretty lengthy and sorta dry as a “scientific” immune system picture book should sorta be, lol.
Also, awesome your brother got referenced! That’s pretty sweet
