In general the most recent pets don't drop... but are available in the vendors. I haven't seen the team's work on Eggzavier at this point (I'm reviewing Egg Hunt and various pieces of the Level Cap raises for AL, PL and DL rn), but I would assume that stuff we dropped in 2020 is fair game while stuff that released in the last two or three months will probably hold 'til the next Eggzavier.
