@Hexadoodle The frog says μ∞≈ so i don't think so

Since at the start he says "⌂∞δ" and when the gorilla shows up says "♣⌂∞í" in a panic, I take "⌂" to mean "want", and "∞" to mean "eat".

The Infinity is Want, and the Triangle (more like House ⌂, right?) is "To Here" or something. Since the frog says "◆⌂Γ∞δ". It's about sending something over or coming over.

Honestly it doesn't really matter what it directly translates to, as long as you understand what the symbol is reffering to in the limited text you need to decipher. So as long as someone reading this understands that ◆ = the picture/figure in the picture, I think I did my job ok, hopefully

Thanks for the symbols, added them all in as well as other missing symbols. Still not sure if △ and ∞ are the actual symbols used though

@Ben Bernanke
I'm pretty sure ◆ = Cat, since the only time he mentions it in the conversation is when he is pointing at the Cat picture wearing a wedding dress, but techincally I guess it could be argued that it means Wife. I don't see how it can mean Gem in the context he uses it in though, unless "Gem" meaning "Something Precious" translating into "Wife" or "Special someone", kind of seems a bit far fetched though.

Here's a better symbol for water ≈ and you might call it an "Approximately equal sign".
Here's some other symbols you can use to replace your text versions:
◆
♣
♀
𝅘𝅥𝅯
↑
[
△
ì (As 4thQueen recommended)

And a couple disagreements with some of these: ◆ does not mean cat, but gems, just like how ♣ has been gorilla for the rest of the game. And it might mean "gem" or refer to currrency in general or value. I could be wrong on this one though.

The music note definitely means "green" as it can be used to identify one of the crates in the room.

The symbol is actually ì, not í.
