L-Luka...!?Say, why don't you tell us about that octopus of yours?Octopus?Oh yeah, what about that little cute/gross looking guy?It's really cute when you carry it around on your arm!And having an octopus must be cheaper than having a tuna, huh Luka?Yeah, you're right! Tuna is better after all! (sorry!)
TUNA! IT HAS TO BE TUNA!!
