Kaloula pulchra — Banded Bullfrog
Some other names for this species:
Malaysian Narrowmouth Toad, Chubby Frog, Rice Frog, Bubble Frog, Ox Frog, Painted Bullfrog, Piebald Digging Frog, Asian Painted Frog, Malaysian Painted Frog, Asiatic Painted Frog, Malayan Banded Bullfrog
I think this frog might be winning the competition for most English names. (My favorite is "Chubby Frog".) It is widespread in southeast Asia, but has only been introduced to Borneo fairly recently.
