Touhou Live A Live - Question and Stuff Thread

[Polnyanski]

Pardon Me for creating this thread, since I don't found any thread about Touhou Live a Live in this forum other than this thread here
https://www.shrinemaiden.org/forum/index.php/topic,16309.0.html
But since that thread last post is in March 2014, so I think I should create a thread here

Now, here is my question

i have some question that has been bugging me when i'm playing the Mokou chapter recently

When I'm playing the Mokou chapter, from what I check in the touhou a live wiki in the japanese wiki, it says that the YDMT-IV (the mecha yukkuri one) has another skill called Maelstrom.
Here is the wiki link : http://www21.atwiki.jp/touhoulal/pages/177.html
To get this skill, you must get the Octopus Board, which is an equipment you get from appraising item from Rinnosuke.
However, to get this specific "Who Knows What" , it says that it must be a drop from the Seilent Base (Eientei), which from playtrough so far, I've never got one from that base, only able to get the Who Knows What from random encounter in the village

My question is, how do you really get this Octopus Board? Is this really from a drop item? And from which enemies?

*Looks into old thread you linked to, having no idea what 'live a life' is*
*Reads the list of scenarios and this 'hnn... interesting.'*
*Notices Ran has a story, downloads instantly*
Umm... I'll get around to playing that, I guess. Looks like a fairly interesting RPG.
(Obviously, I can't answer your question :V)

*Looks at info*
Shouldn't it be according the Katakana, "Soylent Base", as in Soylent Green.
Anyway, you must get the Who Knows What from the Soylent Base to make it available but it's not from an enemy drop
(the wiki only say you must get 1 Soylent Base' Who Know What and then appraise, something like that).
Instead, it's well hidden in there.
This Let's Play (which covers optional content from various scenario and thus contain SPOILERS) show you the location :

If you don't have an account there, use a redirector like this one :

Start looking from at least 12:35 up to around 13:00.
Optional boss might or might not be needed to be defeated to gain access to this place.

Really, Let's Plays can get really convenient when you need to get info from Japanese games. ^^

Also. the Octopus Board is a reference to SaGa Frontier where said item apparently give nifty bonuses to Mechs.

I see, thank a lot for the information, finally I can move to the other scenario

Since I'm going to play the Meiling and Ponga Scenario, is there any missable stuff and easter egg that i have to pay attention?

I want to achieve 100% run for this game, and I remember in the other scenario there's a lot of missable stuff as well, so I guess I'm going to need your help

I am not very familiar with the game but I would at the very least watch the video in my previous post for some info on bonus stuff.
Also, perhaps watching other video from this "My List" could help you see if you missed something :
