I think, but not known to occur this far north? Unfortunately lost and couldn't get additional photo. Approx 1cm. Yellow spotting on cerata with red bases

The kids called it a jelly pony...pretty sure that's not right, but we have no idea!

私人的描述
La Paz, B.C.S., Mexico
Three of these, found together under a rock with sparse hydroids. Each only about 2-3 mm - quite small. At first, I thought they might be odd Tenellia albocrusta. (B.C.S. is the southern range limit of C. albocrusta according to Gary’s iNat guide: https://www.inaturalist.org/guide_taxa/933633#ref2)
But the thing that gave me pause was how extensive the opaque white speckles are - extensively down the oral tentacles (not seen in any other photo of C. albocrusta on iNat) and the entire length of the rhinophores. All three had the same markings.
In Camacho-Garcia, Gosliner and Valdes, “Guia del Campo de las Babosas Marinas del Pacifico Este Tropical,” 2005, p. 105, a tiny Cuthona Sp 6 looks like a possibility - the photo isn’t reproduced well, but there seems to be white on the oral tentacles (not mentioned in the text, so I may be seeing something incorrectly) and white spots on the rhinophores are mentioned. I haven’t seen more recent information on this Cuthona.
From TGosliner: "This looks like something entirely new to me! It certainly is not Tenellia albocrusta. The head shape and ceratal color are entirely different. Very cool!"

Tiny nudibranchs eating/laying? even more tiny spiral egg masses on the underside of the sand collar. Given that it’s preferred food is Harminoe eggs and those egg masses were all over where we found the Olea, my money is on these spiral masses being Olea eggs rather than their food (also the small aggregation of individuals) @anudibranchmom ID

HELLO AGAIN.
This is now the second time I've photographed this undescribed nudibranch - the first one was found by Luan Roberts when we were dock fouling in August 2021: https://www.inaturalist.org/observations/91369989
Unfortunately I did not have collecting materials with me, and I couldn't detour via CAS, so it got to go about its nudibranch business after these photos were taken.
This mystery slug does not appear in Behrens et al, Eastern Pacific Nudibranchs, 2021, nor have I found any references to it elsewhere.

A group of these nudibranchs feed on a cluster of Zyzzyzus rubusidaeus hydroid polyps. Note the cluster of their eggs at the lower left.

Found by @luanroberts. About 7 mm. Orange bands on white-tipped oral tentacles, orange bands on the white-tipped rhinophores, and white specks on the surface of the body.
Obelia and Tubularia (Pink-mouth hydroid) present elsewhere in the marina in small quantities, but didn't see it feeding.
Looks vaguely like the pale one in the left-side photo on Page 124 of Behrens & Hermosillo's Eastern Pacific Nudibranchs, 2005. Same individual as https://www.inaturalist.org/observations/91332884
Update: this hydroid https://www.inaturalist.org/observations/92299348 was the only hydroid on the boat bumper where it was found.
