Recognise the Tree Frog variant
Lost Province’s guide pairs the Tree Frog and Poison Dart Frog and shows them as separate appearances. The final image in the Tree Frog route shows a green frog with red eye rings, a pale belly and blue-orange side markings. The orange frog with dark limbs is shown at the end of the separate Poison Dart Frog route, whose method uses snowballs.

For the other animals and frog-family rewards, use the character list and skin overview.

Follow the recorded trampoline route
Select the original frog
Equip the starter frog before bouncing. Both unlock guides specify the normal/original frog; do not substitute a different frog variant during the attempt.
Get a trampoline prop
The dedicated May guide buys a trampoline at the lodge prop shop and records a 30,000-point price. Read the price on your own shop screen before purchasing.
Place it in the nearby fishing igloo
Lost Province uses the fishing igloo near the lodge and places the trampoline under its roof. This is the author’s practical setup for repeated bouncing, not proof that the igloo is a separate unlock requirement.
Bounce and watch for the reward
Stay near the trampoline centre. AttackOnMars and the original frog video report 100 bounces; Lost Province reports 200. Keep the original frog equipped and use the actual unlock message to determine when the attempt has succeeded.

Verify the reward in character selection
Open character selection and look for the separate green frog with red eye rings. The source inventory shows it beside the orange Poison Dart Frog and the other starter and unlocked characters. Select it and check the visible character; your own inventory is the completion check, even when a counted attempt differs from an old guide.

If it is still absent, confirm the starter appearance and that you are actually bouncing on the trampoline. Record the build and session details before repeating a long attempt. For progress that disappears after reconnecting, use the lost-progress checklist.
