Pandas spawn with a randomized personality, with the normal personality being the most common and the brown variant being the rarest. The personality depends on genes. Each gene has the same distribution on spawn as the mutated gene. So the probability of each personality is:
Baby pandas have Template:Frac chance to drop 1 Template:ItemLink after they sneeze. This means that, on average, a weak baby panda produces a slimeball every 4 hours, 51 minutes and 40 seconds, and any other baby panda produces 1 every 58 hours and 20 minutes.
Pandas follow any player that is carrying Minecraft:bamboo and stop following if the player moves beyond approximately 16 blocks away. Pandas produce a whimper sound effect if a thunderstorm is happening in the area.
Baby pandas have a Template:Frac chance (0.016%) of sneezing every Minecraft:game tick. Weak baby pandas are more likely to sneeze with a Template:Frac (0.2%) chance every tick. Sneezing makes all adult pandas within 10 blocks jump and rarely drops a Minecraft:slimeball. Baby pandas also occasionally roll over and jump around.
Pandas have one private inventory.
A Minecraft:lead cannot be used on a panda by normal means.<ref>Template:Bug</ref> However, a panda can be leashed using a map editor or Minecraft:NBT editor.
Are slower than normal pandas, making them the slowest land mob in the game.
Do not follow a player who is holding Minecraft:bamboo while they're lying on their back.Template:OnlyTemplate:IN, if a Minecraft:player is holding bamboo, a lazy panda stops lying on its back and starts following that player.
Roll over and jump around even as adults. The ability to roll may sometimes cause harm or kill the panda as it can accidentally roll off a cliff or into other environmental hazards.<ref>Template:Bug</ref>
Identifiable by their thick eyebrows and tight frown.
When hit, an aggressive panda attacks the Minecraft:player and other mobs continuously until the target dies or goes beyond detection range, instead of only once. It also doesn't panic when harmed.
When nearby pandas are attacked, unless killed in one hit,Template:Only aggressive pandas become hostile toward the attacker.
Are slow, but have Minecraft:reach rivaling that of the player.
Do not have unique personality actions, but are brown and white instead of the usual black and white.
Breeding
The panda is the only animal to have extra Minecraft:breeding conditions. Template:IN, pandas enter love mode when fed with bamboo, but breed only if there is at least one Minecraft:bamboo plant (not including shoots) within a 7×7×3 area; otherwise the pandas briefly shake their heads and do not breed until that requirement is met. If only one panda is close to a bamboo plant, the other panda shakes its head, but a baby is born.
Template:IN, there must be at least 8 bamboo plants within a five-block radius of each panda in order for them to enter love mode. If a panda is fed without a sufficient amount of bamboo plants nearby, it sits and eats the bamboo instead of entering love mode.
Once pandas successfully breed, they produce a baby panda that remains neutral toward that Minecraft:player.
Additionally, if a worried panda is mounted, and the baby zombie variant doesn't have a target, the worried panda keeps running as if trying get away from its passenger, since it avoids all mobs, including monsters.
Genetics
Each panda has two hidden values called "Template:W" or "alleles", as found in Template:W. Pandas have a main gene and a hidden gene, each assigned to a particular trait. Normal, aggressive, lazy, worried, and playful personalities are dominant traits, while weak and brown personalities are recessive traits. If the main gene is a dominant gene, then it presents as the personality regardless of the hidden gene. If the main gene is recessive and the hidden gene is not the same trait, then a normal personality results. As recessive traits, weak and brown personalities occur if both the main and hidden genes of a panda are weak or brown, respectively. The hidden gene is relevant only for determining the panda's personality if the main gene is recessive.
When two pandas breed, each one passes one of their genes to their children, who then randomly mix both obtained genes as their respective main and hidden genes. There is also a Template:Frac chance for each gene of the baby to mutate into another gene. Normal, weak, and brown traits more commonly result from mutations than other traits do. These probabilities also apply to naturally spawned pandas for their main and hidden genes.
The only way to directly observe the hidden gene of a panda (if they are not weak or brown, in which case the genes are certain) is to use the command : Template:CmdTemplate:Only or using third-party NBT editors.
