on your neopets day, there are certain things that your pet can have for free. For example, once on ruki day you could train your pet in the swashbuckling academy for free the whole day. On other neopets days, you could get big discounts in shops or get free items or go to the training school (another place to train your pet) totally for free! On limited edition neopets days (only tonu cybunny draik hissi and kiko) you can create a pet and choose those pets in the limited edition section.
The weight of the watermelon on Neopets is varied day to day. Try searching 'Neopets Watermelon' or 'Neopet finders, cheats, and guides' on a searched engine.
