Giant Octopus is a Chimera horse.
Tame this horse in order to age it, train it, take it for rides, and enter it into competitions. You can also ask other owners of a Chimera horse to help you progress faster. Help others in return and increase your Chimera horse's skills.
Once tamed, this horse will give you 10 
for each horse year until age 80. The reward can appear on any of the buttons for horse care when waking up.
In spring and summer, Giant Octopus may refuse some of the care you try to give them and thus lose energy.
Korosensei cannot be sold.
