This might be one of the biggest balloons I've tried, inflated and decorated.... a Russian 45" in light blue, tho I am not sure they inflate 45", but here it was inflated at 100cm (about 40") it was massive.

I drew Swallowmon, a design for a Digimon fanfic, I like this design a lot, I drew her in chubby form here and enjoyed drawing her ^_^
