Headscratchers / The New Adventures of Winnie the Pooh

• In "No Rabbit's a Fortress," why didn't Gopher simply dig a tunnel under the fortress? It certainly would have saved them a lot of trouble.
  • There have been several instances of Gopher's tunneling backfiring on those inside. Perhaps they just wanted to play it safe?
• Watching the series for the first time in about a decade after getting a Disney+ subscription, my Mom, sister, and myself have started to wonder about something. Are the events depicted in the show supposed to be really happening or is this a situation similar to that depicted in Calvin and Hobbes?
  • The idea behind the whole franchise is that The Hundred Acre Wood is just in Christopher Robin's imagination, so there ya go.
• In the Episode where Tigger loses his stripes, what exactly made him lose them? He took a bath when he lost them, and any other time he takes a bath/enter water they don't disappear. And at the end of the Episode when he's getting his stripes back, they explode back onto him (they at least sound like explosions when they reappear). So what exactly happened that made his stripes disappeared?
