Spongebob Bikini Bottom ID Tee

Educational resources & donation included with every purchase. Learn more.

Made in California from 100% ringspun organic cotton and screen printed using algae ink (water-based ink using black bio-based algae pigment), providing a soft hand feel and excellent wash durability. Algae Ink is a net negative carbon technology, with each bucket of ink sequestering the same carbon as two trees!

SpongeBob was created by marine biologist Stephen Hillenburg, who used art to teach kids about the marine species and ecosystems around them. With its origin in marine science education, the series has always had a deep-rooted connection to the sea. This connection led Paramount and Nickelodeon to launch SpongeBob SquarePants: Operation Sea Change, a global conservation and sustainability initiative to help protect the home of the very creatures that inspired Bikini Bottom. We created this collection in partnership with Paramount Consumer Products to support the Operation Sea Change initiative as well as advocate for the importance of art in inspiring environmental stewardship.

Global Organic Textile Standard (GOTS) Certified, the worldwide leading standard for organic textiles like cotton. GOTS certification ensures our cotton is pure and ethically sourced and is made without chemical pesticides, forced labor, child labor, or unfair wages.

Advocate Apparel Inspired by the Bikini Bottom Ecosystem

The SpongeBob SquarePants creative team did such an incredible job designing the ecosystem of Bikini Bottom with its distinctive bright colors, iconic flower-shaped clouds, and buoyant mood that our team wanted to embody it when designing the SpongeBob Bikini Bottom collection. Although a fictional world, Bikini Bottom and its citizens are inspired by real underwater critters and places, many of which can be found in the intertidal zone.

Besides being huge fans of the show for its creativity, positivity, and forward-thinking themes, we love SpongeBob SquarePants as an example of how art can support environmental science and conservation. Art can provide an opportunity to instill emotion and humanity into science communication while maintaining its scientific integrity. Art can speak for animals, ecosystems, and communities who may not be able to speak for themselves. Art can transform apathy into enthusiasm, enthusiasm into action, and action into change. And in special cases when an artistic expression becomes widely popular like the animated adventures of a charismatic sponge, it can inspire an entire generation.

Exactly as pictured. Very cute.

This shirt arrived exactly as pictured, true to size, and made of very high quality material. It’s so cute I’m sharing it with my daughter I stead of giving it to her outright :)

10/10 quality product, fast shipping

I saw the pre-order for this shirt on Facebook and knew it would be the perfect gift for the Spongebob fan in my family. I ordered it on Jan 11, knowing it wouldn't ship until Jan 23. It arrived Jan 25! I was surprised that it arrived so quickly. It's soft, the print quality is amazing and it has me seriously debating about buying one for myself. 10/10 would recommend the shirt and Waterlust to my friends.
