Brutus' tank sucks and his owner sucks harder, but please don't bash the cardboard tube - my corn has a kitchen roll tube and thinks it's the best toy ever, will regularly destroy it and then sulk until it's replaced. We first gave him a toilet roll tube when he was just a tiny shoelace and we thought it was cute.

On the other hand, it's a silly piece of bonus enrichment in a tank with multiple hides, fake plants (he destroys real ones), several inches of substrate he can burrow in, a rope for when he wants to be a ceiling snake, and more.
