Candyland is a wonderful place where the currency is lollipops. They have flying cars and a victorian style that brings out your inner Britishness. It isn't located in any verse but in an alternate dimension that can be accessed through the Alternatehistoryverse. Mr. Delightful is from here.
As it turns out, Mr. Delightful has proven the oscillating verse theory true. He comes from a dimension where his infinitiverse came before the one we see today instead of the other way around. It can actually be accesed by time travel exactly one infinitiverse lifetime in the future.
