My level is too low

Keep up the good work! If you have 3 fragments, they'll be needed for this event, so demand is high. Also, while waiting for recovery, they're likely to be touched or petted easily. As your level increases, you'll only be able to collect fragments once per friend, which can make managing your energy a hassle in a different way (if you touch a symbol that can't be collected, you also can't touch it again until 24 hours have passed or it becomes collectible).
