Modding Help How would I make a mod with custom status effects, leading to an item being spawned, and buffs/debuf

So I'm thinking of making an alien style mod with the Erchius things, with a simple pixel animation of a chestburster at the end.

I was thinking of a simple object that when consumed, has a % chance of causing the 'infected' status to be applied.

After a certain time and some debuffs, an animation will play and the creature will emerge, spawning an object to be placed in the inventory. The object can be interacted with and 'fed' with health or some kind.
