Interesting. Gonna follow waiting for an android version.
Btw, the Panda's shirt quoting is a bit wrong.
太い is used for "thickness", not really for "fat", and the phrase structure is not in the correct way, specially the Past Tense in 太った, since it suggest he was fat, not anymore.
So the most appropriated phrase would be 大きな脂肪パンダ.
