Welp, I just remembered something I loved about this site, which is that they tend to make items in reference to popular games, movies etc. I've already seen a couple Undertale related items and was wondering if anyone could help me find a complete list of all the Undertale related items on this site, also, wondering if there are any Five Nights at Freddy's related items, and if there are, if I could get a complete list of those too? Googling this has resulted in absolutely jack diddly. Thanks guys. ^_^

you might try https://subeta.net/forums.php/read/824259/-TributeReference-Items-Thread-v30 for both

the only undertale item i know offhand is the flowey plushie (friendly flower plushie) in the millionaire center, but i'm sure there's others

Alrighty, yeah it was the flower plushie that made me wanna seek out others that might be related. Thanks for the link, that is actually perfect because now I can see all the other cool reference items I might like as well. ^_^

as far as i know, the flowey plushie is the only undertale reference item, at least so far. there's also this CW:

There's a Flowey tribute CW too:

There's also an Undyne Spear CW tribute I came across:

Apart from the CWS mentions above,

also references Undertale.

Actually after awhile I just found two more that I'm certain are references, the Blazing Blue Nazar and the Traditional Red Nazar.

those items are from 2011. undertale only came out this past september, so they're definitely not intended as references. certainly appropriate, though.

Oh wow, I didn't know how long ago they came out. They looked so coincidental I thought there was no way they weren't a reference. Thanks for the info. ^^
