About this template
Explore the tide pool with this spiny sea urchin! Its round body ringed with pointed spikes makes a fun, patterned shape to build. It's an easy project for ages 5–7 who love ocean creatures. Kids can drag tiles into place online or press printed stickers onto the sheet. Deep purples and maroons make this little urchin look right at home on the reef.
