Island Days

The sequel to Bubble Bobble , Rainbow Islands sees Bub and Bob who were turned into human form at the end of its predecessor, attempting to rescue the inhabitants of the titular Rainbow Islands from the evil Boss of Shadows.

Instead of bubbles, Bub and Bob now have the power to cast rainbows, that can be used to directly destroy baddies or trap them underneath.

The Nintendo 3DS (2011) added glasses-free stereoscopic 3D and a second analog input to Nintendo's handheld line, eventually building a library that rivaled the DS in size and quality. Because the eShop for digital purchases has since closed, physical 3DS cartridges are the only way to preserve access to many titles — a dynamic that's pushing more collectors toward cartridge-based copies even for games that were originally digital-first.

Gamevaro tracks Island Days for Nintendo 3DS with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.

Adding Island Days to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This 3DS release dates back to 2014.

Only a handful of market sales have been tracked for Island Days, suggesting it doesn't trade hands very often — a sign of relative scarcity compared to more common Nintendo 3DS titles.

Complete-in-box (CIB) copies typically command a premium over loose cartridges/discs because the original box and manual are more fragile and get discarded or damaged over time — fewer complete sets survive.
