In Mendelian genetics, dominant alleles are represented with capital letters meanwhile, recessive are represented in lowercase, also it doesn't specify if it´s complete dominance, or incomplete dominance, therefore, we will assume the most basic case: complete dominance. That is to say when there is a dominant allele (capital letter) the trait shown will be the one that the dominant allele has, the recessive trait will only be shown in absence of the dominant trait, so there will have to be two lower case letters.
List of traits, alleles, and phenotype.
Eyes (Ee): Two small eyes
Eye Color (rr): white eyes
Skin Color (Bb): Blue skin
Tail shape (CC): Curly tail
Tail color ((PP): Purple tail
Tail (Tt): Have tail
Teeth (SS): Sharp teeth
Feet (Ff): Feet with four toes
Horn Color (Ww): Purple horns
Ear shape (Yy): Pointy ears
Ears (Nn): No ears
Claws (Ll): Long claws
Finally, it is coded the color and/or shape for ears and tail, however, is also coded if has or not ears and tail, so in this case says it has no ears (Nn), in that case, the character for ear shape is irrelevant because there are no ears, in this particular case, if you would have obtained a monster with ears that character makes all sense.
