'SpongeBob SquarePants' Merch for Grown-ups

SpongeBob SquarePants merchandise doesn't have to look childish, even though his target demographic is decidedly young, even adults love SpongeBob SquarePants. The absorbent sea sponge has been a worldwide phenomenon since he premiered in 1999 on Nickelodeon. Patrick, Mr. Krabs, Sandy and Squidward round out the main characters of Bikini Bottom.

SpongeBob has earned fans of all ages, so rather than sift through all the kiddie toys for an appropriate gift for a grown-up, here's a list of SpongeBob SquarePants gifts any adult fan would love.

Like an iPod Shuffle, this micro version of SpongeBob's blazing eye has 1 GB, which can hold about 250 songs. Also comes with a clip in case you're going for a jog.

The first season of SpongeBob SquarePants includes my favorite episodes, such as "Bubblestand," "Tea at the Treedome," "Hooky" and "Rock Bottom." Plus, fans will enjoy fun bonus features, such as the Violent Femmes singing the SpongeBob theme, recollections from the crew, a Bikini Bottom tour and Karaoke.

Let your friends and family experience birthdays, Halloween and Christmas, Bikini Bottom-style with SpongeBob, Patrick, Sandy and the rest of the crew in Holidays With SpongeBob, a 3-disc collection of themed episodes, which include classics like "I Was a Teenage Gary" and "Christmas Who?"

This 7" digital photo frame comes with two interchangeable frames you can stick to the outside of the digital frame (or just leave it off). But the coolest part is that you can program transitions between photos that scroll characters across the screen. Fun!

Gather round these popping eyes of SpongeBob to listen to your favorite playlist. Or leave them in to let SpongeBob peep at you. What could be more grown-up than that?

Your favorite golfer will never have trouble distinguishing their golf balls from their buddy's. SpongeBob's bright yellow color and wide-open eyes will keep these balls visible on the golf course.

For fans who may want their devotion to SpongeBoB SquarePants to be displayed subtly, this cute, clever keychain is perfect. Not only is the keychain of Patrick instead of SpongeBob, but the LEGO label is ultra-hip now.

A SpongeBob SquarePants calendar will cheer any fan every day of the week. Especially when it's posted at the office or tacked up at home. Lots of SpongeBob SquarePants calendars feature trivia and quotes.

Tired of your friend or family member spouting off SpongeBob quotes? This handy SpongeBob SquarePants trivia book will help them pass the time when the in-laws come to call. Or, make a game of it by testing each other.

No, the jokes in this book don't come directly from SpongeBob SquarePants episodes. However, they are sea-themed and approved for all audiences. Kill 'em at work without offending anyone.
