These are individual blinkie block letters you can use to make some words.
Read this (important)
Each of the sets of blinkies shown below have all of the letters in them. The letter A is shown as a preview. To change the set and letter, in the code look for rb_star/rbspics2/blinkie_names/set1/a.gif. Change the set number to the one you want and the letter 'a' to the letter that you want to use. To use more than one letter, you need to copy the whole code again and change the set/letter to the one you want. (only use lower-case letters, for example use r, not R)

Paste the code on your HTML editor. To find out where that is in neopets, click here.
