Hey,
I see you've already got an answer to your question. Additionally, given that this was also already answered in the Easter Event thread and in this thread:
Watchfire Building (Easter Egg Trade-In Store), I'll close this one in order to avoid duplicate discussions.
If you have any further questions with regards to the Easter Event, please read through the
Easter discussion thread. It is a very long thread and a lot has been answered there already. Feel free to join the discussion there.
In particular, you may want to check out
this post (click here), which contains very useful information about the items available in the trade-in store.
P.S. Moving this to the FAQ section where it belongs.
