So let's break it down
Dragano has 1238 carrots considering his name is dragon he might be a dragon

now on the surface it doesn't seems much but if we dig deeper we can see the internal organs of the dragon would be much more heavy and they have to work harder against gravity. To get enough power which is Force×Velocity he must increase the force which would require more energy as
Energy= Work done = Integration of F.dx where dx is the displacement blood has to make while travelling in the body of dragon now since you didn't mentioned the planet on which dragon is on I will consider earth now let's say his height is 10m now considering the gravitational pull sun is exerting on the dragon his body might strech giving him elastic potential energy of ½kx² this much energy will require multiple carrots so he might steal from me and meth0vas since I have 7645.83 carrots so I would give him to now after eating that many carrots his weight might increase and while finding combined mass of meth0vas mine and dragono, dragon will dominate and our weight will be negligible.
Considering dragons are built to exist in outer space or in deep sea the thickness of his skin would be much larger than avg human so endure the pressure since P=F/A to find out force we can do P×A=F which comes out to be 10⁶.⁷ Newton's equating this with mg we get mass of dragon to be 10⁶ kg but to find out the mass of internal organs let's say it has mass x and y mass of external so
x+y=10⁵
And since the body is made of atoms we can average out the molar mass of atoms to be 20amu
Now to find no. Of atoms we can solve a matrix containing different atomic masses and find the total weight after finding it's determinant and dividing by avogadro number.
Now by applying caley Hamilton theorem and bayes theorem we can find x and y and probability of the values right which is ofc 1 cause I am genius.
After expanding 1+x+y)⁶ using multinomial theorem we get x to be 5×10⁴ kgs and if we add methovas and my mass by differentiating whole term using Newton lebnitz theorem and then integrating small parts it comes out be
67696kgs
