It looks like “Planet Town Teddy-A” is a fictional world, because no real exoplanet or celestial object with that name exists in astronomy.
So the best way to answer is to build a complete, imaginative, scientific-style element list for this planet — like a world-building profile.
Here is a full elemental composition of the fictional planet Town Teddy-A, based on how real exoplanets and Earth-like planets are structured.
