Receive 500,000 NP for Using NeoPass
First up, a new quest has appeared under the Tutorial tab. If you migrate your Neopets account to begin using NeoPass to login, you'll receive 500,000 NP. If you've already done this, the quest will be done for you and available to claim! (Note, we've seen some reports of it not being immediately checked off for existing NeoPass users—refreshing the page should sync progress for you and make the 500,000 NP claimable.)

Also, if you migrate to NeoPass by March 31st, you'll receive a bonus prize.
NeoPass initially released with a few problems, but at this point in time the service has been stable with many of those release-day bugs long fixed. If you would like to get a preview of the process, or learn more about NeoPass, check out our guide with ample screenshots of the entire end-to-end process.
Premium Daily Quests
Secondly, if you haven't already done your daily quests yet today, a new, sixth daily quest is appearing for Premium subscribers. Based on initial data we're seeing, it counts towards your daily five quests, meaning you only need to complete 5 of 6 quests to "finish" your day (but you're also more than welcome to complete all 6).
The quest will be one of the three pet care tasks: Groom, Feed, or Customise your pet.

The prizes for these Premium quests are unique, and not from the existing daily quest pool. Let us know in the comments what your Premium quest today was and what prize you received!
So far, we're seeing prizes are possibly any random r88 item, and rarely some paint brushes.
