So a while back I discussed the idea of these tomogachi-like creatures for the game called Woomies:

Quick recap: Woomies (like I said) are these tomogachi-like creatures that you can both raise and have fight along side you/Leah.
And I don't know if I've stated why they are called Woomies, so I wanted to clear it up here.
They are called Woomies because you can activate a CG with them where they slither into and live inside Leah's Womb, as well as pop out of it.
(I should probably let you all know in advance that I'm not an animator by any means)
For example this is one of them going inside of Leah: ↴

And here's is one of them coming out of Leah: ↴

Please let me know if it still doesn't make any sense and I'll try to clear things up for you.
