Sticky Frog is a material found in Tears of the Kingdom.
Tears of the Kingdom
"This frog likes to cling to walls and hang out. It oozes a substance that climbers can use to cling to wet surfaces."
Sticky Frogs can typically be found near bodies of water in caves around Hyrule.
They can be cooked alongside monster parts to create Elixirs. When cooked with a monster part that has no specific enhancement, such as a Bokoblin Horn, Link will create a Sticky Elixir. This will temporarily give Link slip resistance.
