bloom spider -- restores 10% hp and 50% stamina (despite not having any blood or meat, it's satisfyingly crunchy and contains a decent amount of refreshing juice)

gloom lizard -- restores 50% hp (has some meat and blood in it, the blood is cold though)

doom bat -- restores 100% hp (not a lot of meat but lots of blood)

torrent snapper -- either heals or damages 75% hp, if eaten grants extra 25% fys armor (plenty of meat and cold blood, but protected by a sturdy shell that will definitely break your teeth)
