Happy Dude

This kid was described as "insanely happy" when I found him. Seems about right. He says "10th Greeting Cards, Inc" on the bottom and is from 1976.

Qik

Qik is from a Wendy's kids meal that teamed up with something called Leapfrog Leap School in 2012. It's the same graphic on each side so he is neither goofy nor regular. Just a 2D guy trying to skate a 3D world.

Sibell Chips

Sibell is a French company that make a wide variety of chips. Croquez La Différence! An anthropomorphic bag is seen here pushing and holding its hands in a weird position.

Rabbit

Skating bunny. No info on this dude at all - thought it might be donut related by color and sprinkle-like shirt but could not track it down. No markings either.

Bart Simpson VI

Bart Simpson mini bobblehead from a vending machine. This is from series 5 - 2006.

Fristi

Fristi is a "milk drink" sold in Belgium and the Netherlands. A foreign Wikipedia article describes it as a "pink beverage" with the flavor of strawberry, raspberry, bramble, apple, grape, cherry and berries. This pin is pretty rad though.

Milo

Milo is from a British show called Tweenies, a muppet type show geared towards kids from the late 90s/early 00s. This figure was a McDonald's Happy Meal toy from 2003.
