Quark has this feature where you can grab a chicken and put it on your head and it gives you slow falling. Chicken Grab Evolved allows other entities to be grabbed and used in this manner. by default it's just the chicken, but you can add other entities in through the Quark config menu. since most entities probably won't look that great when grabbed in first person, there's a separate (configurable) list of entities that won't be rendered in first person when grabbed. please note that since Grab Chickens uses the vanilla passenger system this will prevent entities on the list from rendering in first person regardless of how they ended up riding a player
this mod was made in like a day for a personal modpack so i can't really guarantee that it's any good but it's simple enough and i'm pretty sure it works
