The weedy sea dragon has bright blue stripes against an orange-red background, and numerous white spots and yellow markings.

There are numerous spots. The best place would be to sell them online on your local Kijij website. You can also list them on Ebay, but you will have to pay sellers fees there.

There are numerous spots to look. The best place for labels is at staples depot or business depot. You can also try their online website staples.ca.

It's called granulation. (Also, I think it's actually a separate thing from the bright spots.)
