It's created with 'vitalized', I'm not sure what that is, but you have to look for episode 83.
This is my first submission, so be nice? :|
A little explanation on the character; just to clear up any misunderstandings.
Mimmi (the kangaroo girl- YES KANGAROO SHE'S NO CAT OR DOG!-) is carrying her new friend TC around in her pouch. She's naked because, well, many reasons. The main reason is because she can't carry someone in her pouch if she's wearing clothes.
Therefore, there is no sexual content in this animation although it may look like it >.>
