Just like the title have said, Mr. Thickly the Wallaby is putting down the Épée on the glass retail display case full of knives and daggers. As usual, he is window shopping for the right blade so that he could defend his friends. Luckily, he's a proper window shopper that is looking for something reasonable later on when he would have time to window shop or purchase anything with a low price. My pal 50PercentGrey suggested that Thickley can have a hunting knife that looks Kukri (Most Khukuri blades are forged in Nepal normally but Crocodile Dundee has a similar weapon I hear) since he mentions it. Besides that, It is a nice weapon for most hunters in Australia (and all of Tasmania included) would like to use for defeating large and predatory animals later on. I guess that the sword and shield and armor and spats are way too expensive since Bushwhacker Bob acts like a cheapskate in a way. Besides that, Thickly thinks of the budget when he finds the right tool with a bargain price or something like it. By the way for those that have played the Kingdom Hearts games, Donald Duck's Centurion blade (this dagger looks like Lexaeus' Skysplitter blade that is an axe sword hybrid really) has made a brief cameo in the case also. You know how Warner Bros Incorporated would like to give Disney stuff some cameos (lawyer friendly cameos included) in their show, right? Which knife will Mr. Thickley buy? What would any Warner Brothers fan say to that? What would Taz the Tasmanian Devil or Constance Koala or anyone in Tasmania think? I'll let your imagination decide on his choice of the blade that he can afford. This is also for the Australian People that have seen this cartoon.
Edit: Pardon me viewers but thanks to Grey's feedback and his new suggestion, I added TazMania's alligators into this pic. Yes, Bull Gator and Axl are managers or proprietors of the weapons shop and Bull (the short and blue alligator) is wearing his red neckerchief along with his black henschel and black gloves and brown sleeveless jacket. Axl (the tall and green gator) is also an assistant manager in his usual pith helmet and red neckerchief. They are suggesting and discussing about the weapons for Thickley and Axl comments about how the Kingdom Hearts cameo weapon can serve as a wizard staff like Donald Duck and he thinks that it can go well with Goofy's shield or Vexen frozen pride. I'll let your imagination decide on how much he has to afford these small blades.
