What do you do with the worms on Neopets

If you mean the worms in Moltara, then you have to get a free lantern at Lampwyck's Lights Fantastic. If you don't get it the first time, then you have to try again. The person says it is crappy and has a bad light source (or something like that). You put the worms in this. There are many worms; in the caves there are purple, blue, pink, yellow, and black, and the city has green, red, orange, white, and rainbow. The black and rainbow are the hardest to find. Then you must go to your inventory and select the lantern. Click the option "fill with worms". Then you must go to to the cave near the middle of the picture at the very top and get the red moltite. You can go back to the lantern shop and trade the crappy lantern for a wearable one. The next day you can get the lantern back and enter the cave again (after the worms have rested) to get more red moltite.
