it looks like a native mexican/latam/caribbean calabaza pumpkin: green with stripes.
there are many that you never see in stores, except for mexican in spanish/mex/latam markets. it is much sweeter then other pumpkins/squashes.
kabocha also has this coloration, but it is usually very squat.
here's a site with great pics! of many-many. perhaps, you can find yours?
