The Groovy Mobile is Slafer's beloved car and favorite mode of transportation. It has a storage compartment which Slafer stores several strange objects such as a ceramic clown head, a leprechaun hat, a matchbox car and a spare doorknob. It is introduced in Slafer's Groovy Mobile and made a cameo in Slaferade/ Slurpee Smoothie Shake. Due to its "compact and steamlined design", Slafer cannot fit in and has his friend, Brachiosaurus drive erratically. It is navy blue, with a yellow roof and a face on the front.
