Why does the squirrel say 我才不是吃货?
才 http://www.cantonese.sheik.co.uk/dictionary/characters/529/
[4] certainly; indeed

'货' can be used as a 'derogatory term (貶詞)' for 'person'. (货 = goods = thing) referring a person as a 'thing'.

'这货' = '这傢伙'

'这(货)沒救了' = This (person) is beyond help

吃货 is a term for 'gluttony' (a person who can really eat alot)


&quot;我才不是吃货&quot; means &quot;I certainly am not a gluttony&quot;
&quot;只是这个好吃&quot; means &quot;But this thing is delicious&quot; (therefore I can't stop eating it)

When we use '才' for 'certainly' the following is always a negative rebuttal
Example:
我才不信 =  I certainly don't believe
我才不幹 = I certainly won't do it
我才沒向老師告密 = I certainly did not rat to the teacher
