I've completed all the steps up to the one about translating the text for the Wizard and have the net in my inventory.

I went to the Greenhouse again, but it's still stuck on the bit about giving Nico the camera parts.

Is there any way I can get to the next step?

Go to Esther's shop and click Talk to Esther, then go back to the greenhouse.

I'm not sure what I did (maybe it's exactly what you said?) But I unlocked them :D. Thanks ^^

No problem c: Thanks for all the flowers! I'd send some back but I literally just finished dumping them all on a friend haha

You're welcome :D. It doesn't matter if you send any back, but it would be nice if you did. I felt like doing smoething 'evil', and that was my evil deed for the day XP
