Pantherlilly can talk or goad Gajeel into almost anything, no matter how stupid. He’ll accept kiwi as bribes. Natsu has used this to his advantage for pranks. 

See also- Pantherlily is older than Gajeel and likes to get his kicks fucking with him either for old man reasons or because someone else asked him to, no bribes required. Its his given right to mess with Gajeel.
