Show off your love for Scooby-Doo! with this EXCLUSIVE Scooby-Doo! Mansion Mayhem tee shirt! Available in toddler, youth, and adult sizes... each shirt is 100% cotton, and a medium-weight tee to ensure a wonderful softness to the cotton and durability without being too heavy or stiff! The Youth and Adult shirts are a darker blue (the same color in fact, the lighting in the photos makes the youth look a bit lighter), and the toddler shirt is available in a lighter blue / teal color.
