ideas for the upcoming 26.4 (i think .4 update) icologer/penguins

I'm pretty excited for the new ice caves as its something I've wanted for a while now kind of like how terraria has and i appreciate the zombie variant as well. I really feel like this update would benefit from things like adding the penguin and iceologer. If the copper golem can make it in these two absolutely should there's no other update more fitting for them.  

other suggestions i have that might fit would be ice/snow bricks or building blocks of some sort. I've played mods with these as options and i think it could be a cool addition 

I have seen concepts for an undead/frozen polar bear i think it was. Something like that could also be really cool and let the new zombie ride it and hold spears 

but I'm mostly focused on the penguin/icologer I know a lot of other people would like to have them they are just too fitting for the update.

ice ball when thrown on water making ice platforms like the ice bomb in education edition could be cool or just add ice bomb
