Special on an ID L

Okey so i have my id l for a few months now, but because of being sick all the time (because of my pregnancy)

I haven't had a lot of time to discover things on it, play with it, etc.

So anyway, today is the first of october and i went to the park, 3 little, green and weird looking guys showed up and they gave me some green sticks ??? What are they?

I discovered them in the "special" menu under the treasure chest.

What is this "special" menu, i've been looking on google and things, but couldn't find any explanation????

What can i discover/ put in here? Does anyone have a list of what goes in here???

Thx in advance !!

On every first day of each month, it's Green Day.

You can receive one of three items.

Basically you will get food in the gotchi restaurant for 50% the price.

Look on page 13 in the instruction booklet. There, you can see the three items available from the EcoUsatchi. Depending on which model (English, Japanese original version, 15th Anniversary ver., Princess Spacy ver.) you have, you may receive Special gifts when you visit certain travel destinations (which get unlocked after you've obtained a high enough number of entries in the TaMaToMo book.)
