Hey guys! Quick question, does anyone know of these logos for these toys?

They have a diamond near their "thigh", located here

(My hands look weird! XD)

And does anyone know which brand these come from?

If you know, then please comment below! It's for a OC's toy that her twin sister owned, but ended up with my OC when she got pushed into another dimension by said twin sister...... Hey, what are sisters for, right? 😅

Thanks for any help you give me!
