Supplemented by input from Venti, Raihan has taken to calling the living fruit Slimeberries. Zhongli has also taught him about Tevyat's elements, which has led to him calling the subspecies of each slimeberry a weird combination of the element + what he recognizes the berry to be.

Purplish-blue -- Chectro (Chesto + Electro)
Reddish-orange -- Pyri (Pyro + Cheri)
Pinkish-green -- Dechdra (Dendro + Pecha)
Yellowish-brown -- Gersim (Geo + Persim)
Ocean-blue -- Hyran (Hydro + Oran)
Light blue ring pattern -- Crysper (Cryo + Aspear)
Greenish-yellow -- Aneppa (Anemo + Leppa)

I think I figured out which berries you guys used based on the flavour text, but let me know if I misread!
