I like crab call as well just for it sounding confused and stressed, which is something I tend to be often so it becomes a mood. However, I don't spam it unless a friend encourages it or I see them on and run over screaming to hug them.
SPOILERS: I like to use the default honk during the end cutscene when youre flying after eden, cause your skykid can sing along with the end song if you spam it, and that just sounds nicer with the default honk
I personally like default honks instead of Crab and Jelly fish honk cause those two are high-pitch that sometimes gives me a headache I just use the Crab if I'm angry and Jelly Fish If I'm sad like honking to find someone help open a door like "Help me 😭(Jelly fish Call)" and "Don't go! 🤬(Crab Call)" As a matter of fact honks has a specific mood/emotion meaning to me: Default: I'm feeling fine Bird: I'm feeling happy Fish: I'm feeling Relaxed Manta: I'm feeling Excited/Joyful Jelly Manta: I'm feeling a bit Sad Crab: I'm feeling mad or pissed Jellyfish: I'm very sad Well those are my Skykids emotions I usually use the Crab if like a moth a hold me and expecting me to help them find Spirits and Wings but they won't behave and keeps on letting go of my hand or like a person is afk in a 4 player's door or 8 Player's door. I never use the honks for Personal feeling like honking at someone using crab call and cursing them in real life 😂 I can curse them in all Honks. Calls are just really my Skykids Feelings. XD
I like default honk and the spirit manta honk, but as a ✨ beta child of light ✨ my new favourite call may or may not be arriving in the upcoming season 👀🙈
You do lots of things, there's kind of a lot to explain but in the simplest way possible: you explore each realm looking for spirits and reliving their memories, by doing this you can unlock cosmetics that are related to those spirits, "cosmetics" are what we basically call clothing items, you can also unlock "calls" which you will release when you click on your character (the video shows a call being used), you can use expressions to communicate, you can make lots of friends, and more :). You should join a sky discord server (I suggest nastymold's or the official sky discord). Good luck!
