Steven's Ukulele is an instrument that belongs to Steven. It first appears in the pilot and makes its official debut in "Serious Steven". Steven occasionally plays it during songs such as "Water Witch" and "Jam Buds".
Steven's ukulele is a four-stringed ukulele. It is embellished with pale yellow, light-orange and salmon-pink wavy designs. It has a maroon strap connected to the back of the ukulele. The center of the ukulele is surrounded with a salmon-pink ring.
Steven brings it along on his "serious" mission and uses it to play "Serious Song".
The ukulele appears to be strapped on Steven's back as he exits the Crystal Temple, and is seen again when he reaches It's a Wash. The ukulele is seen multiple times again when Steven continuously warps back in time.
The ukulele appears in Greg's Van, held by Steven.
