Slam

Slam is best remembered for their track "Wild Riders of Boards," which appeared (and named) Thrasher's 3rd skate rock compilation. Slam hail from Sweden and started releasing material on their own Slam Records in the mid '80s. In 1987 they self-released the End of Laughter LP, which was also released by Seattle's Subcore Records in the US (Subcore also released the original version of the Accüsed's The Return of Martha Splatterhead). The LP features an alternate version of "Wild Riders" and features the above artwork in the insert.

Wafflesaurus

49% waffle, 51% dinosaur, 100% skateboarder. This Eggo dinosaur is printed on a floppy rubber frisbee from 1992. I'm not sure if he is actually called a Wafflesaurus but it seems like he probably is. 

Robby Rabbit

Robby Rabbit is an uncommon Sanrio character first introduced in 1976. He seems to always chill with this bee dude but I can't ascertain if the bee has a name. I actually can't find much of any info on Robby himself; apparently he just wasn't cute enough to cut it next to Hello Kitty and her ilk. At any rate, Robby is doing a 1-footed wheelie on blue side of this coin purse. The red side finds him holding his board.

Down by the Bay

The Imposters 2nd appearance on BPA comes in the form of their 3rd 7" EP.  Unlike their debut 7", which features a great pool skating action shot, this cover features the 3 band members sitting with their boards (including a Santa Cruz era Duane Peters). The 7" was released in 2011 on Richmond's Headcount Records. Although the cover pales in comparison to their first skate cover, the record itself delivers 3 excellent surf punk tracks.

California Sports Duck

This duck is a Kinder Surprise and is part of a set of ducks participating in "California sports." You can see what all that entails below, but most seem to be just be associated with warm weather. He's got a derpy eye thing going on, although I don't think that is on purpose.

Edit: I think these are supposed to be chicks. From 2007.

The Champion

The Champion is a keychain of a monkey riding a board. The board has a battery in it and made the board light up. This feature worked when I first took him out of the package (there was a battery-saving spacer to remove). 24 hours later he no longer worked. 24 hours after that he partially lit up. 24 hours after that he worked no more, which is the state he remains in today. His board says e-Bape, which I have yet to figure out what exactly that is, but they make some other monkey-themed toys.

Reason of Insanity / El Desmadre

Florida's Reason of Insanity and Texas's El Desmadre released this split 7" EP on the Death Exclamations! label in 2008. Both bands play straight-forward hardcore punk. The cover features a skateboard amid a crowd scene of zombies, sort of like an undead version of What Happens Next? debut 7".

Troll Doll

Troll Dolls have been around since '59 and have rode multiple waves of popularity. It was only a matter of time before someone nailed one to a skateboard. This guy was made by Russ and although he's riding an early '80s pig I think he might be from the '90s.
