Sorry to be the negative person, but ball sizes for cum transforms are inaccurate for the height and weight of the characters. These are height and weight estimations, but they are more accurate.
Mice-5 gal of cum
Sheep-6.6 gal of cum
Rat- 10.42 gal of cum
Kangaroo-11.35 gal of cum
Guard Dog- 12.62 gal of cum
Giraffe- 16.21 gal of cum (I know the Giraffe is tall but is also quite skinny so I took a 5'8" weight even though its probably 6')
Shark- 17.37 gal of cum( Though shorter than the Giraffe she has more weight on her but only by a gal so I took a 5'10" weight)
Dragon- 22 gal of cum ( As tall as the Giraffe, but same body type as the Shark so I took a 6'2" weight)
here is how much cum each character would look like it a bucket https://www.google.com/search?sca_esv=598988451&sxsrf=ACQVn08uFBDpIarURoqvLnoCLs...
