If you would create one or more tokens, you may instead create that many 2/2 green Cat creature tokens with haste or that many 3/1 green Dog creature tokens with vigilance.

Secret Lair Drop

The tokens' characteristics are entirely replaced by either 2/2 green Cat creature token with haste or 3/1 green Dog creature token with vigilance. They don't have any other abilities the tokens would have been created with. Anything else specified in the effect creating the tokens (such as tapped, attacking, “That token gains haste,” or “Exile that token at end of combat”) still applies.
